D-A dyad and D-A-D triad incorporating triphenylamine, benzanthrone and perylene diimide: Synthesis, electrochemical, linear and nonlinear optical properties
To study the relationship between donor (D)-acceptor (A) structures and the third-order nonlinear optical property, two types of D-A and D-A-D structures based on triphenylamine-substituted chromophores with benzanthrone or perylene diimide (PDI) acceptors have been designed and synthesized. Among them, D-A-D type chromophores with a linear configuration show relatively larger two-photon absorption (2 PA) coefficient and 2 PA cross section value. (C) 2017 Elsevier B.V.
