摘要

通过含有二位活性氢的 DPP 与三位芳基醛的 Knoevenagel 缩合，开发出了基于四烯链二酮吡咯并吡咯（DPP）的 CMP。分子框架中的 "四烯 "π排列促进了不间断的π异位，从而产生了近红外（NIR）吸收（约 1200 纳米的红边）、原始状态下（10-3 S/m）和掺杂状态下（0.2 S/m）的高导电性以及适度的能量存储（70 F/g）。

Near-IR absorbing Tetraene-linked π-Conjugated Porous Polymer 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-infrared (NIR) absorption (~red edge of 1200 nm), high electrical conductivity in pristine (10-3 S/m) and doped states (0.2 S/m), and moderate energy storage (70 F/g).
