Nonlinear Optical Response Properties of Aryl - Substituted Boron -Dipyrromethene Dyes: Unidirectional Charge Transfer coupled with Structural Tuning [PDF]

, 2016
Controlling the nonlinear optical (NLO) response properties at the molecular level is a key to develop strong NLO active materials for technological applications. In this paper, we report quantum chemical investigation of NLO response properties of select aryl-substituted Boron-Dipyrromethene (BODIPY) dyes, a class of intramolecular charge transfer ...
