Near-IR absorbing tetraene-linked π-conjugated porous polymers for energy storage and electrical conductivity

Chem Commun (Camb). 2024 Dec 17;61(1):125-128. doi: 10.1039/d4cc05074f.

Abstract

Tetraene-linked diketopyrrolopyrrole (DPP)-based CMPs were developed via Knoevenagel condensation of ditopic active hydrogen containing DPP with tritopic aryl aldehydes. The "tetra-ene" π-arrangement in the molecular framework promotes uninterrupted π-delocalization, resulting in near-infrared (NIR) absorption (∼red edge of 1200 nm), high electrical conductivity in the pristine (10-3 S m-1) and doped states (0.2 S m-1), and moderate energy storage (70 F g-1).
