Abstract

Free-standing covalent organic membranes (COMs) with β-ketoenamine (TAPA-Tp), imine (TAPA-DTP), and vinylene (NTB-PDAN) linkages were interfacially fabricated, and their linkage-dependent nano-conductivity was probed using conductive atomic force microscopy (CAFM). The COMs exhibited excellent electrical continuity, with NTB-PDAN (15.78 pA) demonstrating superior nano-conductivity over TAPA-DTP (0.56 pA) and TAPA-Tp (0.42 pA).
