  Systematic Structure–Property Investigations on a Series of Alternating Carbazole–Thiophene Oligomers

  摘要：

  A series of alternating carbazole-thiophene oligomers, namely 2,7-linked carbazole-thiophene oligomers 1, 3, 5, 7, and 9 and 3,6-linked ones 2, 4, 6, 8, and 10, in which the molecular length was systematically elongated, were synthesized by Suzuki-Miyaura coupling reactions. The effects of the conjugation connectivity between the carbazole and thiophene moieties and the molecular length on the electronic, photophysical, and electrochemical properties of 1-10 were comprehensively investigated. In the present oligomer architectures, the connection with thiophene at the 2,7-positions of carbazole ensures pi-conjugation to a high extent and high fluorescence quantum yields, while that at the 3,6-positions enhances the donor ability. The increase in the molecular length of the 2,7-linked oligomers effectively extends pi-conjugation. The relationship between structural variations and photophysical properties was examined by fluorescence lifetime measurements in detail. The X-ray crystal structure of 6 was also disclosed.

  electrochemical, thermal and electroluminescence properties. The thiophene containing dyes showed red-shifted absorption and emission profiles than that of the phenyl analogs due to effective electronic delocalization in the former. Also, the thiophene-based dyes exhibited low oxidation potentials than that of the phenyl analogs attributable to electron richness. Electroluminescence devices were fabricated

  The thermal, optical, electrochemical and charge transport properties of a series of nine straightforward carbazole-based compounds have been analysed and interpreted according to their molecular structure by means of the X-ray analysis of single crystals. A non-doped OLED device with low turn-on voltage and maximum luminance up to 1.4 x 10(4) cd m(-2) was achieved. DFT calculations have been performed to explain the high efficiency of radiative exciton production. (C) 2016 Elsevier Ltd. All rights reserved.
