Заглавие : New push-pull systems based on indolo[3,2-b]carbazole and 1,2,4,5-tetrazine: synthesis, photophysical, and charge transport properties

Ключевые слова (''Своб.индексиров.''): 1,2,4,5-tetrazines--nucleophilic substitution--indolo[3,2-b]carbazole--push-pull systems
Аннотация: 5,11-Dihydroindolo[3,2-b]carbazoles were for the first time modified with acceptor 1,2,4,5-tetrazine fragments. The photophysical and charge-transport properties of the synthesized donor-acceptor heterocyclic systems were studied. It was shown that the introduction of the 1,2,4,5-tetrazine moieties makes it possible to increase the hole and electron mobility by one and two orders of magnitude, respectively, as compared to analogous 5,11-dihydroindolo-[3,2-b]carbazole derivatives studied previously.

Заглавие : Synthesis, crystal structures and properties of carbazolebased [6]helicenes fused with an azine ring

Ключевые слова (''Своб.индексиров.''): azine-fused helicenes--carbazole-based [6]helicenes--helical structures
Аннотация: Novel carbazole-based [6]helicenes fused with an azine ring (pyridine, pyrazine or quinoxaline) have been prepared through a five-step synthetic sequence in good overall yields. Commercially available 2,3-dihaloazines were used as starting materials. To discern the effect of merging an azine moiety within a helical skeleton, the X-ray structures, UV–vis absorption and fluorescence spectra of the helicenes were investigated and compared to that of the parent carbazole-based [6]helicene (7H-phenanthro[3,4-c]carbazole).

Ключевые слова (''Своб.индексиров.''): 5,11-dihydroindolo[3,2-b]carbazole--thiophene--3-chloroacrylaldehyde--the vilsmeier–haack formylation--the fiesselmann reaction
Аннотация: A series of new 5,11-dihydroindolo[3,2-b]carbazole derivatives, containing functional thiophene, 2,2′-bithiophene or 2,2′:5′,2″-terthiophene moieties at both C-2 and C-8 positions of their fused scaffolds, have been obtained from 2,8-diacetyl-substituted 5,11-dihydroindolo[3,2-b]carbazole compounds through the effective strategy, which is based on the sequence of two reactions, namely the Vilsmeier–Haack formylation and the Fiesselmann thiophene synthesis. The starting acetyl substituted materials have been transformed into the corresponding 3-chlorocrylaldehyde-containing compounds by treatment with POCl3-DMF complex, followed by the reaction with alkyl thioglycolates or α-mercaptoacetone in the presence of triethylamine to afford 2-carboalkoxythiophene- or 2-acetylthiophene-linked derivatives. 2-Acetylthiophene derivatives have further been involved into the same sequence of reactions to obtain 2,2′-bithiophene-, and 2,2′:5′,2″-terthiophene-linked 5,11-dihydroindolo[3,2-b]carbazole compounds.

Ключевые слова (''Своб.индексиров.''): imidazoles--carbazoles--absorption spectra--photoluminescence--tddft calculations--charge mobility
Аннотация: New 3-(1H-imidazol-2-yl)-9H-carbazoles and 6,6′-di(1H-imidazol-2-yl)-9H,9′H-3,3′-bicarbazoles have been prepared, starting from 9-ethyl-9H-carbazole-3-carbaldehyde or 9,9′-diethyl-9H,9′H-[3,3′-bicarbazole]-6,6′-dicarbaldehyde through their reactions with 4-methoxyaniline or 4-fluoroaniline, benzil or 2,2′-thenil [1,2-di(thien-2,2′-yl) glyoxal] and ammonium acetate on reflux in glacial acetic acid. The obtained compounds have been shown to demonstrate an effective fluorescence in the blue spectral region, exhibiting quantum yields in the range of 0.08–0.51, depending on their molecular structure and solvent polarity. The nature of the observed absorption spectra has been elucidated by the TDDFT calculations.

Аннотация: A series of new polycyclic compounds bearing the 5,11-dihydroindolo[3,2-b] carbazole ring system, as the common motif of their nine-ring scaffolds, has been successfully prepared with the usage of an efficient two-step strategy, based on the double Friedel-Crafts acylation of 5,11-dihexyl-6,12-di(hetero) aryl-substituted 5,11-dihydroindolo[3,2-b] carbazoles with 2-iodobenzoyl chloride in the presence of SnCl4, followed by regioselective palladium-catalyzed cyclization of the obtained 2,8-bis(2-iodobenzoyl) derivatives into the desired fused 9H-fluoren-9-ones. Some modifications of these nine-ring structures have been performed to afford compounds of the same family bearing the 9H-fluorene fragments. Basic photophysical and electrochemical properties as well as thermal stability of the new fused indolo[3,2-b] carbazole derivatives have been determined.

Ключевые слова (''Своб.индексиров.''): pyrimidines--carbazole--dye-sensitized solar cells
Аннотация: Novel donor-pi-acceptor dyes bearing the pyrimidine unit as an electron-withdrawing group have been synthesized by using combination of two processes, based on the microwave-assisted Suzuki cross-coupling reaction and nucleophilic aromatic substitution of hydrogen. Spectral properties of the obtained dyes in six aprotic solvents of various polarities have been studied by ultraviolet-visible and fluorescence spectroscopy. In contrast to the absorption spectra, fluorescence emission spectra displayed a strong dependence from their solvent polarities. The nature of the observed long wavelength maxima has been elucidated by means of quantum chemical calculations. The electrochemical properties of these dyes have been investigated by using cyclic voltammetry, while their photovoltaic performance was evaluated by a device fabrication study. The experimental and calculation data show that all of the dyes can be regarded as potentially good photosensitizers for dye-sensitized solar cells.

Ключевые слова (''Своб.индексиров.''): indolo[3,2-b]carbazole--indole--thiophene
Аннотация: Novel 5,11-dialkyl-6,12-di(thiophen-2-yl) substituted 5,11-dihydroindolo[3,2-b]carbazoles have been obtained and plausible ways for their further modifications via the Friedel–Crafts reaction are presented. The formylation of these indolo[3,2-b]carbazoles with dichloromethyl alkyl esters catalysed by Lewis acids leads to the formation of the corresponding 2,8-diformyl derivatives. Applicability of this formylation method for modification of indolo[3,2-b]carbazoles bearing electron-rich aromatic substituents at C-6 and C-12 has also been demonstrated. The Knoevenagel condensation of 2,8-dialdehydes with active methylene nitriles has been studied. The measurements of optical and redox properties for a number of new indolo[3,2-b]carbazoles have been performed
