Synthesis and physical properties of zethrene derivatives bearing donor/acceptor substituents at 7,14-positions.
نویسندگان
چکیده
Zethrene derivatives substituted by phenylethynyl groups bearing electron-donating and/or accepting groups were synthesised by iodine-induced transannular cyclisation of dehydrodinaphtho[10]annulene as the pivotal step followed by Sonogashira coupling reaction. Their physical properties were investigated to elucidate the effects of the substituents on the electronic configuration of the zethrene backbone.

Crystal structure of 7,15-bis(4-tert-butylphenyl)-1,9-dimethylheptazethrene
The title compound, C50H44, 1, was synthesized as a derivative of hepta-zethrene bearing two methyl and two tert-butyl-phenyl substituents, respectively, at the 1,9- and 7,15-positions. The asymmetric unit consists of one half of the mol-ecule, which lies about an inversion centre. Albeit remotely located, the substituents contort the hepta-zethrene plane. The tert-butyl-phenyl substituents sta...
متن کاملZethrene and dibenzozethrene: masked biradical molecules?
The syntheses, structures, and physical properties of dibenzozethrenes were explored. The results thus obtained were compared with those for zethrenes. Dibenzozethrenes were synthesized by the nickel-catalyzed cyclodimerization of 9-ethynyl-1-iodoanthracenes. The substituents in zethrene and dibenzozethrene twisted their backbones, and remarkably influenced their properties. Unlike closed-shell...

A series of 1,7-bis(arylethynyl)-N,N'-bis[2,6-diisopropylphenyl]perylene-3,4:9,10-bis(dicarboximide)s has been obtained from Sonogashira coupling of the 1,7-dibromoperylene-3,4:9,10-bis(dicarboximide) with p-substituted phenylacetylenes in which the p-substituents include pi-donors (dialkylamino, diarylamino, p-(diarylamino)phenyl, alkoxy) and pi-acceptors (diarylboryl, p-(diarylboryl)phenyl). ...
متن کاملThiophene-functionalized isoindigo dyes bearing electron donor substituents with absorptions approaching the near infrared region.
A series of six new, highly soluble N,N'-dialkylated isoindigo derivatives bearing different electron donating thiophene units at the 6,6'-positions were synthesized by Stille cross-coupling reaction. The optical and electrochemical properties of these dyes were studied by UV-vis spectroscopy and cyclic voltammetry, revealing a good tunability of their electronic properties by peripheral substi...
متن کاملDonor-acceptor substituted phenylethynyltriphenylenes – excited state intramolecular charge transfer, solvatochromic absorption and fluorescence emission
Several 2-(phenylethynyl)triphenylene derivatives bearing electron donor and acceptor substituents on the phenyl rings have been synthesized. The absorption and fluorescence emission properties of these molecules have been studied in solvents of different polarity. For a given derivative, solvent polarity had minimal effect on the absorption maxima. However, for a given solvent the absorption m...
