Triphenylamine-based allylidenemalonitrile chromophores: Synthesis, photophysical and second-order nonlinear optical properties.

Abstract

A series of chromophores based on a mono- di- of tri-substituted triphenylamine core and allylidenemalonitrile fragments has been designed. The linear and second order nonlinear optical properties as well as thermal stability of the chromophores have been studied experimentally. Structure-properties relationships, in term of branching effect on the triphenylamine core and the influence of aniline/coumarin part on the photophysical properties and NLO response have been highlighted. Experimental results have been rationalized by theoretical calculations.
