  Synthesis and photophysical properties of a series of thermally stable terphenyl-bridged bisbenzimidazoles

  摘要：

  Nine novel terphenyl-bridged bisbenzimidazoles were synthesized in high yield by the condensation of o-phenylenediamines and teiphenyl dinitriles in the presence of polyphosphoric acid The bisbenzimidazoles are thermally robust with high decomposition temperatures (>346 C) and high melting transitions and emit blue light at 410 nm with fluorescence quantum yield >0 4 in solution Electrochemical studies indicate that the novel bisbenzimidazoles have a formal reduction potential in the range of -144 to -155 V and estimated electron affinities (lowest unoccupied molecular orbital levels) of 3 09-3 24 eV The results indicate their potential use as blue emitting materials in organic light-emitting diodes (C) 2010 Elsevier Ltd All rights reserved
