A series of monomeric copper complexes that allow for the tuning of the emission properties is reported. Luminescence lifetimes up to 150 [mu]s are observed in benzene solution at ambient temperature, which are comparable to the lifetimes of the longest-lived previously reported copper luminophores. These complexes also exhibit quantum yields up to 0 = 0.70 at 298 K. The results of time-dependent density functional theory (TDDFT) calculations indicate emission from a triplet state in all cases. The calculations also successfully correlate the energy of the transition from this triplet state to the energy of the observed emission. Such luminescence from a first-row metal is highly unusual, especially when considering the phosphine-based ligand framework used.

Повний текст джерелаLa spectroscopie de fluorescence s'est avérée une technique précieuse pour étudier la structure et la fonction des acides nucléiques et d'autres molécules essentielles en biologie cellulaire. À cet égard, les analogues de nucléoside fluorescentes intrinsèques sont largement utilisés pour sonder les propriétés structurales et dynamiques des acides nucléiques. À cause de ses propriétés émissives uniques, 6-phénylpyrrolo-2'-déoxycytosine (dPhpC), un nouvel analogue fluorescent de la déoxycytosine, est un reporter fluorescent approprié qui a été exploitée pour étudier la structure, la dynamique et la localisation des acides nucléiques. dPhpC possède plusieurs propriétés souhaitables, notamment le rendement quantique élevé et une sensibilité à des changements dans le micro-environnement environnant. Compte tenu de la demande croissante de discrètes sondes fluorescentes pour utilisation dans des études biochimiques, dPhpC est un fluorophore attrayant qui imite la cytosine par rapport au couplage d'acide nucléique de base et les interactions enzymatiques. Pour utiliser cette sonde moléculaire à son plein potentiel, il est essentiel d'élucider les interactions entre dPhpC et ses nucléotides voisins inter- et intra-brin, et l'effet de ces interactions sur les propriétés fluorescentes de dPhpC. Avec cette information, dPhpC peut être utilisé comme une sonde moléculaire très sensible pour l'étude d'une grande variété des systèmes à base de acides nucléiques, et les oligonucléotides fluorescentes contenant du PhpC peuvent être facilement optimisé à des fins spécifiques. Dans cette thèse, nous avons synthétisé 6-phénylpyrrolo-2'-désoxycytidine (dPhpC) et l'ont incorporé dans l'ADN simple et double brin. Ce travail démontre que la nature et l'orientation des voisins nucléosidiques entourant dPhpC affecter de manière significative ses propriétés fluorescentes. Selon les résultats présentés dans ce travail, les rendements quantiques de fluorescence moyenne pour dPhpC contenant des simples brins est supérieure à celles de leurs doubles brins correspondants. Plusieurs règles pour la prédiction et l'optimisation des propriétés des oligonucléotides contenant dPhpC sont également identifiées: l'adénine voisin entraîne une augmentation significative de l'intensité de fluorescence de dPhpC, la guanine plus efficacement étanche fluorescence, et l'orientation des voisins autour dPhpC affecte de manière significative le rendement quantique de dPhpC (par exemple l'effet d'extinction de la guanine est plus élevée lorsqu'il est placé à l'extrémité 3 'du côté dPhpC). Dans l'ensemble, nos études permettez-nous de prévoir mieux les changements de fluorescence de dPhpC sur l'incorporation en structures d'ADN, ce qui facilite grandement la conception d'optimisation dPhpC contenant des sondes d'acides nucléiques pour utilisation dans une grande variété d'études de fluorescence.

ABSTRACT Many enzymes require cofactors in order to carry out specific functions. Flavins, which are naturally fluorescent, compose a unique group of redox cofactors because they have the ability to transfer one or two electrons and are therefore found in three different oxidation states. A specific flavin, flavin adenine dinucleotide (FAD), is a crucial cofactor that facilitates electron transfer in many flavoproteins involved in DNA repair, photosynthesis, and regulatory pathways. One example of a FAD-containing DNA repair protein is DNA Photolyase (PL). E. coli PL is a monomeric flavoprotein that facilitates DNA repair via a photoinduced electron transfer reaction. The catalytic cofactor, FAD, transfers an electron to a thymidine dimer lesion, to cleave the cyclobutane ring and restore the DNA strand. Although the mechanism of repair has been partially elucidated by our group, it is still unclear whether or not the electron is transferred directly from the isoalloxazine moiety to the dimer or if the electron hops from the isoalloxazine moiety to the adenine moiety to the dimer. This sequential hopping mechanism should have excited state absorption features for the reduced flavin species, an adenine radical anion, and the semiquinone flavin species. To investigate the mechanistic role of adenine, E. coli PL has been reconstituted with -FAD, an FAD analogue in which the adenine was substituted via chemical means with 1,N6 – ethenoadenine dinucleotide. -FAD was selected due to its ease of synthesis and because its structure changes the thermodynamic driving force for the electron transfer reaction, by lowering the energetic gap (LUMO-LUMO) between the isoalloxazine ring and the modified adenine. In order to characterize the excited state dynamics of the mutant chromophore, the transient absorption measurements were made of each free flavin in solution. These measurements indicate the pathway of electron transfer must be mediated via superexchange rather than a hopping mechanism. This important result shows that the role of adenine in photolyase is to facilitate a superexchange electron transfer mechanism, and a modified flavin can act as a reporter under these experimental conditions. By exploiting Corynebacterium ammoniagenes FAD synthetase adenylation promiscuity, we have enzymatically-synthesized and purified a novel dually fluorescent flavin cofactor. This new flavin adenine dinucleotide (FAD) analogue, flavin 2-aminopurine (2Ap) dinucleotide (F2ApD), can be selectively excited through the 2Ap moiety at 310 nm, a wavelength at which flavins have intrinsically low extinction. The dinucleotide 2Ap emits at 370 nm with high efficiency. This emission has excellent overlap with the absorption spectra of both oxidized and reduced hydroquinone flavin (FlOX and FlHQ respectively), which emit at ~525 and ~505 nm respectively. We have characterized the optical properties of this dually fluorescent flavin, iFAD. Steady state fluorescence excitation and emission spectra were obtained and contrasted with the other flavins. Temperature- and solvent-dependent emission spectra suggest that F2ApD stacking interactions are significantly different compared to FAD and etheno-FAD (FAD). The optical absorption spectra of these dinucleotides were compared with FMN to explore electronic interactions between the flavin and nucleobase moieties. To probe the evolution of the different excited state populations, femtosecond transient absorption measurements were made on the iFADs, revealing that F2ApD exhibited unique transient spectra as compared to either FAD or FAD. The significance of these results to flavins, flavoprotein function, and bioimaging are discussed. The reconstituted -FAD in E.coli photolyase was catalytically active and actually repaired more efficiently than the FAD-reconstituted photolyase. To validate that an enzymatically synthesized iFAD could be reconstituted into a flavoprotein, this work shows a DNA repair assay using F2ApD that was reconstituted into E. coli photolyase, generating the reconstituted analogue, ApPL. Activity assays were compared between FAD-PL and ApPL. This comparison further elucidates the importance of the driving force on the electron transfer reaction in PL. A comparison of fluorescence spectroscopies between the reconstituted PLs highlights their applicability as biosensors and/or mechanistic reporters.
