Abstract

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.

• 💡 PEI-functionalized COFs (TpPa–SO₃H@PEI600-40%) show proton conductivity up to 5.9 × 10⁻³ S cm⁻¹ and low activation energy (0.14 eV) at 98% RH and 80 °C, with excellent stability in water vapor. ⚡💧 [bsky, 0 points, 0 comments]
