Abstract

A set of monodisperse 2,7‐linked carbazole oligomers (3‐mer, 5‐mer, 7‐mer, and 9‐mer) was synthesized, and their photophysical, electrochemical, and thermal properties were investigated. In solutions, these oligomers exhibited bright blue emission with almost quantitative fluorescence quantum yield. The emission spectra of these oligomers in films are quite different. 3‐Mer and 5‐mer exhibited featureless emission spectra, whereas 7‐mer and 9‐mer showed well‐resolved emission spectra.

The efficient synthesis of a novel cyclic carbazole tetramer and carbazole main-chain polymer via the Knoevenagel condensation has been developed. The carbazole cyclic tetramer could be obtained in a high yield by a one-stage Knoevenagel condensation of 3,6-diformyl-9-heptylcarbazole and 3,6-bis(cya
