Abstract

Quinoxalino [2′, 3′: 9, 10] phenanthro [4, 5-abc] phenazine (QPP) dyes have been studied as electron acceptor materials, fluorophores, and building blocks for self-organizing organic semiconductors. Condensation of tetraketopyrene with electron-rich diamino- terphenylene and-triphenylene derivatives generates new donor–acceptor QPP derivatives that display columnar mesomorphism over wide ranges of temperature; are fluorescent in ...
