Conformational Freedom‐Enhanced Optomechanical Energy Conversion Efficiency in Bulk Azo‐Polyimides (Adv. Funct. Mater. 45/2021)

Abstract

In article number 2104414, Shangchao Lin, William Oates, and coworkers model the photo-switching process of bulk azo-polyimide using a novel, high-fidelity coarse-grained molecular dynamics framework. The optomechanical energy conversion efficiency is significantly enhanced by the larger initial free volume fraction due to residual stress alleviation and less heat dissipation.
