| 英文摘要 | Two disk-like D-A type chromophores with multi-triphenylamine donors and hexaazatriphenylenes acceptors were synthesized and fully characterized by (1)H and (13)C NMR, elemental analysis and mass spectrometry. The effects of the hexaazatriphenylene oil the optical and electrochemical properties and band gap of the chromophores were investigated. As the hexaazatriphenylene core fused with three thiophene rings, the band gaps of the compounds Could be tuned from 1.65 eV to 1.15 eV. The pi-pi* absorption peak and charge-transfer absorption peak of the hexaazatriphenylene Compounds were Fed shifted from visible spectrum region (393 and 530 nm) to near-infrared spectrum region (542 and 756 nm). In addition, clue to an increase in the pi electronic Coupling between electron donor and electron acceptor, the extinction coefficient (charge-transfer absorption) of the hexaazatriphenylene compound decreases 85% from 3.4 x 10(4) mol(-1) dm(-3) cm(-1) to 0.5 x 10(4) mol (1) dm (3) cm (1).
