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

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-infr...

Description
Summary: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 ). Tetraene-linked diketopyrrolopyrrole (DPP)-based CMPs were developed via Knoevenagel condensation. The CMP has been characterized with NIR absorption (∼1200 nm) and high electrical conductivity (0.2 S m −1 ).
