摘要

BCA顺式配位MOF(1)最初被发现具有电子转移光致变色。光生成自由基（1P）在1158 nm处表现出最大的吸收增强峰，这是由于[BCA]••自由基之间的顺式配位和π-π相互作用诱导的平面π共轭协同作用，从而促进了NIR-II光热效应。

NIR-II absorption and photothermal conversion in a photochromic metal–organic framework based on cis-2,2′-biquinoline-4,4′-dicarboxylate†

A BCA cis-coordinated MOF (1) was initially discovered to exhibit electron transfer photochromism. Remarkably, the photogenerated radicals (1P) showed a maximum absorption enhancement peak at 1158 nm, resulting from the synergistic effects of planar π-conjugation induced by cis-coordination and π–π interactions among [BCA]˙˙ radicals, thereby promoting the NIR-II photothermal effect.
