Fluorescein dyes are widely used in different brunches of chemistry and related sciences, first of all owing to their unique fluorescent properties. Among these compounds, nitro derivatives are much less explored. This work was aimed to disclose the main protolytic and spectral properties in non-aqueous solutions of these dyes.A series of nitrofluoresceins and several amino derivatives, 22 compounds in total, was studied in detain mainly by spectroscopic methods.The behavior of these compounds differs significantly from that of other fluorescein dyes, e.g., very popular halogen derivatives. The shift of the tautomeric equilibrium of the neutral forms of the dyes is shifted toward the lactone. The peculiar feature of the dyes bearing four NO2 groups in the xanthenes portion of the molecule is formation of anionic lactones, caused by the pulling electron density away from the nodal carbon atom. Another feature is the ease of the rupture of the pyran ring in highly alkaline solutions.The values of the dyes were determined by the spectrophotometric method in buffer solutions in DMSO and in several cases in acetonitrile that contains 4 mass % DMSO, at 25 oC.Interpreting the values require an understanding of the state of tautomeric equilibria. For instance, the difference between the values of stepwise dissociation of the dyes, , in DMSO vary from 1.2 for 5'-nitrofluorescein to 7.6 to 4,5-dinito-2,7-dibromofluorescein. The analysis of the absorption spectra in the visible region allows identifying the molecular and ionic structures of the dyes. The evaluation of the fractions of the tautomers made it possible to calculate the so-called microscopic equilibrium constants, describing the dissociation of single tautomers. The last-named coincide with those of model compounds: esters, ether, and a sulfo analogue.A special study was devoted to revealing the transmittance of the electronic effects in the fluorescein molecule by examining the influence of NO2 and NH2 substituents in the phthalic acid residue on the s of the OH groups in the xanthenes part.Introduction of a nitro group in the phthalic part of fluorescein quenches the emission. Surprisingly, the dyes with four NO2 groups in the xanthenes part exhibit bright fluorescence in DMSO and aprotic solvents. As result, a new pH-independent fluorescent indicator, methyl ester of 2,4,5,7-tetranitrofluorescein, very sensitive to the ability of the solvent to hydrogen bonding, is proposed. Also, the conditions of single- and double-charged anions of 5'-aminofluorescein in solutions of different nature are elucidated.The study of a mixture of aprotic and hydrogen bond donor solvents with model compounds (BODIPY) will allow us to further study in more detail the mechanism of the effect of hydrogen bonds on fluorescein derivatives

Detection and fluorescence imaging of biologic systems requires the implementation of efficient, robust and easy-to-use tools. Conventional fluorogenic probes currently used in microbiology lack efficiency since they are based on the single chemical modification of a fluorophore bearing an optically tunable reactive group, which often leads to incomplete fluorescence quenching. The main goal of my Ph.D thesis was to develop novel fluorogenic enzymatic substrates based on the "covalent assembly" principle. This approach also named "in situ synthesis" is based on the use of domino reactions to form a fluorescent moiety starting from a "caged" non-fluorescent molecule. In our case, the bioanalyte that triggers the reaction is present in bacteria, that we want to detect. This strategy provides many advantages (improved signal-to-noise ratio, easy exemplification to a wide range of analytes, …). In this context, the first goal of my thesis was to synthesize original fluorescent hetero-xanthene dyes to assess their stability under physiological conditions. Novel sulfone- and Si-pyronin derivatives were obtained. Synthesis of the corresponding "caged" precursors to the most stable compounds was then undertaken for their use as a peptidase-responsive probes. This work is described in the first and second chapter of this manuscript. Faced with difficulties to implement "covalent assembly" probe design principle to Si-pyronins, another class of fluorophores, namely quinoxalinone was explored. In situ formation of these fluorescent heterocycles triggered by an enzyme is presented in the third chapter. Finally, the last chapter was devoted to the synthesis of a conventional probe derived from a bis-sulfonyl-bis-aniline recently reported in the literature

Three new chemodosimeters 23-25 were prepared, and their chromogenic and fluorogenic behaviors toward various metal cations were investigated. Receptor 23-25 show exclusively response toward Hg2+ ion and also distinguish Hg2+from other metal cations by different color changes in DMSO aqueous solution (DMSO/H2O = 9/1, v/v). Among them, receptor 23 also exhibits a pronounced Hg2+-induced fluorescence enhancement. Thus, the receptor 23 can be use as a colormetric and fluorescent chemodosimeter for determination of Hg2+ ion. The use of the test strip of the receptor 23 to detect Hg2+ was also reported.

Three new sensitive and selective cyanide chemosensors 15-17 were prepared, and their chromogenic and fluorogenic behaviours toward various anions were investigated. Among them, receptor 15 shows exclusive response toward CN- ion. When cyanide ions were added (EtOH/H2O = 3/7, v/v), the pronounced enhancement of the fluorescence, as well as the color change of 15 was observed so that micromolar concentrations of cyanide were detectable by the naked eye. The use of test strip of the receptor 15 to detect CN- ion was also reported.

Part 1. A new chemodosimeter 1-(4-(4-trifluoromethyl phenyldiazenyl) phenyl)-3-(pyren-1-yl)thiourea (20) was prepared, and its chromogenic and fluorogenic behaviors toward various metal cations were investigated. Receptor 20 shows exclusive a response toward Hg2+ ion and also distinguished Hg2+ ion from other metal cations by color changes in DMSO aqueous solution (DMSO/H2O = 9/1, v/v). Additionally, receptor 20 also exhibited a pronounced Hg2+-induced fluorescence enhancement. Thus, the receptor 20 can be used as a colorimetric and fluorescent chemodosimeter for the determination of Hg2+ ion. Part 2. The passionvine mealybug, Planococcus minor is a serious pest of economically important crops in Taiwan. The effective control of this pest is limited by only using pesticides. Also the side effects such as the insect resistance, the pesticide residue and the environment contamination will be occurred. To avoid these side effects, the nontoxic sex pheromone of the passionvine mealybug is chosen instead. The sex pheromone of Planococcus minor was identified as (E)-2-isopropyl-5-methyl-2, 4-hexadienyl acetate (1). The synthesis of this sex pheromone would produce two isomers in the products. This caused some difficulties and troublesome. On our hand, due to the high cost of the starting material and the low yield of the product, the development of a cost-effective, high yield and operationally simple synthetic approach is necessary. In this report a series of new palladium reagents are used for the synthesis of the intermediate, 2-(5-Methylhex-4-en-2-ynyloxy)- tetrahydro -2H-pyran (8). In addition, the subsequent coupling reaction can also be successfully preceded by using FeCl3. This improved synthetic method can overcome the above limitations. Receutly, the effective control of this pest in the tests by using this pheromone is achieved. This indicates that the synthesized pheromone has strong attraetiveness for the passionvine mealybug.
