Abstract

Abstract We report, herein, the synthesis of new push–pull chromophores that incorporate a diazine ring as the electron-withdrawing part and an N, N-dimethylaniline moiety as the electron-donating part. Both of which are connected to a fluorene core. The length of the conjugated backbone was increased by incorporating ethynyl linkers and triazole rings on the both sides of the fluorene. The optical and two-photon absorption (TPA) properties ...
