【 摘 要 】

tsCovalent organic framework (COF) superlattices were assembled by free-standing COF nanofilms based on the van der Waals force for the first time.Geometry-induced “nano-hourglass” steric configuration in COF superlattice can provide rapid charge transfer/accumulation at heterojunction interface for in-Plane Micro-supercapacitors.The prepared MSC exhibited a high energy density of 63.2 mWh cm−3 even after high-angle and repeat arbitrary bending from 0 to 180°.
