Polyethyleneimine functionalized covalent organic frameworks for efficient proton conduction
Proton conductivity in COFs was well modulated by varying the PEI molecular weight and grafted content. Notably, TpPa–SO 3 H@PEI 600 -40% exhibited a high proton conductivity of 5.9 × 10 −3 S cm −1 at 98% RH and 80 °C.
