Molecular Design and Supramolecular Organization of Highly Efficient Nonlinear Optical Chromophores for Exceptional Electro-Optic Properties

摘要

Arene-perfluoroarene stacking interactions are explored in a new series of dendronized nonlinear optical (NLO) chromophores to create extended network structures and overcome intermolecular electrostatic interactions for improving their poling efficiency and alignment stability. These supramolecular self-assembled molecular glasses showed ultrahigh electro-optic (EO) activity (r_(33) > 300 pm/V) and excellent thermal stability (at 85 °C). These unprecedented EO activities could inspire the vigorous development of new integrated optical devices.
