Bulk Azo‐Polyimides In article number 2104414, Shangchao Lin, William Oates, and co‐workers 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.
