Abstract

Abstract : DAST–PVDF Composite Films In article number 2100485, Xiaomeng Cheng, Xiangdong Xu, and co‐workers demonstrate that the interface interactions of the electrostatic interactions and the intermolecular hydrogen bonds between 4‐ N, N ‐dimethylamino‐4′‐ N ′‐methyl‐stilbazolium tosylate (DAST) and polyvinylidene fluoride (PVDF) improve the conjugation of p electrons and molecular ordering of DAST, thus making tunable and long‐term‐stable strong nonlinear optical properties of flexible composite films.
