A molecular engineering principle in which repeat units of fairly rigid fused bicyclic structure and alkenes, separated by freely rotating single bonds, is proposed by Gregory A. Sotzing, Yang Cao, and co‐workers in article number 2000499 for energy storage at elevated temperatures. The piston‐like crankshaft structure endows the system with a large bandgap of ≈5eV and flexibility, while being temperature‐invariantly stable. The piston/pendant allows engineering for temperature‐invariant dipolar polarization for energy storage.
