Full textThis Thesis is focused on the design, synthesis and characterization of new multifunctional molecular materials based on donor-acceptor (D-A) dyads formed by the electron-donor tetrathiafulvalene (TTF) unit linked to the electron-acceptor polychlorotriphenylmethyl (PTM) radical moiety through different -conjugated bridges. These compounds can exhibit interesting physical properties such bistability and nonlinear optical properties in solution, conductivity in the solid state or electrical rectification when anchored on surfaces. Thus, these systems could find potential applications in the field of molecular electronics as switches, conductors or rectifiers. In the first part of the Thesis, we have studied the bistability phenomenon in solution of a D-A dyad based on a PTM radical linked to a TTF moiety through a vinyelene bridge. This system exhibited a temperature-induced switching between diamagnetic dimers at room temperature and paramagnetic monomers at high temperature. The two different states showed different optical and magnetic properties when using the temperature as external input. On the other hand, we have also reported the A-D-A diradical triad based on two PTM radical subunits connected through a TTF-vinylene bridge that can reversibly modify the optical, electronic and magnetic properties by one-electron reduction and oxidation in CH2Cl2 solution. The modification of electron delocalization and magnetic coupling was observed when the charged species were generated and the changes were rationalized by theoretical calculations. In the second part of the Thesis, we have reported the synthesis and characterization of different TTF--PTM dyad derivatives increasing the number of vinylene units between the D and A moieties. We have studied the intramolecular charge transfer and non-linear optical (NLO) properties in solution and their dependence on the open-shell structure as well as on the bridge length for this family of compounds. In the third part of the Thesis, we have studied self-assembled architectures in the solid state of a new D-A dyad based on a PTM radical linked to a TTF moiety through a -phenyl-pyrrole bridge. The crystal structure showed an interesting supramolecular arrangement with segregated donor and acceptor units. Moreover, we reported the appearance of conductivity in single crystals of the same system when increasing the pressure. The semiconducting behavior at high pressures has been attributed to the enhanced intermolecular interactions and charge delocalization due to incorporation of TTF units which force the formation of close packed stacks of molecules. Finally in the last part of the Thesis, we have reported a new TTF-PTM dyad that was functionalized with a disulfide group in order to prepare self-assembled monolayers (SAMs) on gold. These SAMs were fully characterized by different spectroscopic techniques in order to study the electronic structure of the system. Moreover, charge transport measurements through the SAMs were performed in order to evaluate the possible rectification behavior.

Full textLos interruptores moleculares han sido un campo de investigación importante en los últimos años debido a la capacidad de interconvertir-se entre múltiples estados al exponerse a un estímulo (escritura) y modificar sus propiedades (lectura). De especial interés han sido los interruptores moleculares que interaccionan con la luz ya sea para cambiar de estado o bien modificar sus propiedades ópticas en la transformación. Esto és debido a que la luz permite un alto control espaciotemporal al mismo tiempo que és no invasiva y altamente sensible a la detección. Por estos motivos, durante esta tesis se han desarrollados múltiples materiales y procesos fotofuncionales los cuales pueden resumirse en dos partes: Por un lado, el carácter multiestado de una familia de interruptores moleculares (fluoro)crómicos basados en compuestos espirocíclicos zwitteriònicos de Meisenheimer (SZMC) se amplió mediante la identificación de un nuevo estado catiónico, con propiedades ópticas distintivas, que se puede generar tanto electroquímicamente, como a través de la adición de ácido. Además, se investigó el comportamiento termo(fluoro)crómico de los SZMC y se demostró que podían responder tanto a cambios en el disolvente como a la presencia de iones. Este comportamiento multiestado i de respuesta a múltiples estímulos fue utilizado en la preparación de varios materiales fotofuncionales basados en SZMC como: un detector de pH de amplio espectro, dispositivos electro(fluoro)crómicos i sensores iónicos, termales i de disolventes. Por otro lado, se controlaron tres procesos químicos diferentes con interruptores moleculares fotoinducidos de tipo ditienileteno (DTE) mediante luz. Primero, la introducción de un grupo electroacceptor permitió la modulación del pKa de un fenol funcionalizado con un DTE. Segundo el control de una reacción de amidación con dos longitudes de onda fue conseguido con una estrategia similar a la anterior utilizando un ester activado basado en DTE. Este reacciona hasta 24 veces más rápido en el estado cerrado generado con luz ultravioleta (ie. activación con UV) que en el estado abierto que se obtiene al irradiar con luz visible (ie. desactivación con visible). Finalmente, el control de reacciones con dos colores de luz fue utilizado para controlar la reacción de oxo-Diels Alder entre un dienófilo basado en DTE activo en el estado cerrado (ie. activación con UV, desactivación con luz visible) i un dieno generado con luz UV basado en orto-metilbenzaldehido.
Molecular switches have been an important research field in the recent years due to its capacity to interconvert between multiple states through a stimulus (writing) and change their properties (reading). Of special interest are molecular switches that interact with light by either changing their optical properties or reacting as stimulus, due to its noninvasive high spatiotemporal control and sensitivity. As a result, several photofunctional materials and processes based on molecular switches were developed during this thesis which can be summarized in two topics. On the one hand, the multistate character of a family of (fluoro)chromic molecular switches based on spirocyclic zwitterionic Meisenheimer compounds (SZMC) was broadened by identifying a novel cationic state with distinctive optical properties, which could be achieved electrochemically or via acid addition. Moreover, the thermo(fluoro)chromic behavior of SZMCs was investigated and successfully demonstrated that they can respond to certain ions and solvents. This multistimuli-responsive and multistate character was then exploited for the preparation of a variety of photofunctional materials based on SZMCs: wide-range pH detectors, electro(fluoro)chromic displays, and thermal, ionic and solvent sensors. On the other hand, light controlled reactivity with dithienylethenes (DTE) was achieved for three chemical processes. First, the introduction of electrowithdrawing groups (EWG) allowed the modulation of the pKa in acetonitrile of a series of DTEs tethering phenol moieties. Second, a similar strategy allowed for the dual-color control of an amidation reaction employing DTE-based active esters which react up to 24 times faster in the UV-generated closed state (ie. activation with UV irradiation) than in the open state formed under visible illumination (ie depletion with visible light). Finally, two-wavelength control was also achieved for an oxo-Diels Alder reaction between a DTE-dienophile active in the closed state and a UV-generated diene based on orto-methylbenzaldehyde.

Full textOrganic small molecules materials with optoelectronic properties are particularly attractive in the fields of organic solar cells and molecular electronics. Porphyrins and curcuminoids (CCMoids) are prospective candidates in these fields due to their modifiable chemical structures and outstanding properties. In this thesis, the design and preparation of these two families of molecules, together with their self-assembly abilities and potential applications have been studied. In chapter II, two metalloporphyrins (Zn(4R-PPP) and Zn(PPP)) containing long chiral or achiral moieties with carbonyl substituents in the four meso-positions of their porphyrin cores have been synthesized. Then, a complete study related to non-covalent multiporphyrin assemblies has been performed, and initial solution-processed bulk heterojunction organic solar cell experiments were presented. To extend the above study, in chapter III, new porphyrins (TEP and Zn(TEP)) with shorter carbonyl substituents have been investigated and the effect of the length of the ligands in intermolecular interactions was studied, searching how this factor affects as well the OSCs performance. With the same chiral centres in the meso-positions, a porphyrin Zn(4R-CPP) involving carboxylic groups was obtained in chapter IV. And the binary self-assembling systems based on its derivations were achieved through non-covalent interaction or ionic self-assembly towards their potential application as active components in nanomaterials. In Chapter V, CCMoids containing chiral groups, in a similar manner as chapter II, were synthesized. In addition, research towards the achievement of terminal acid groups from the hydrolyzation of the ester groups (as chapter IV shows) allowed the investigation of the possible creation of systems with different dimensionalities. Then in Chapter VI, the synthesis of CPs/networks was explored by the use of a CCMoid containing pyridine moieties at its endings (3Py-CCM). The last chapter is devoted to the design of new porphyrin derivatives containing sulphur-based anchoring groups for their application in single molecular electronics together with the study of their electronic properties in solution and solid state. In addition, a family of CCMoids has also been analysed in a similar manner as the porphyrin derivatives, with the aim of gathering information to improve their molecular design for electronic applications.
