摘要

含(E)-1,2-二（吡啶-4-基）乙烯（Ebpe）的金属氯模板有机-无机杂化晶体表现出明显的光显效应，明显地跳跃在紫外线诱导的[2 + 2]光二聚化上。详细的结构分析表明，金属氯化物组分是一个有效的模板，精确排列Ebpe分子，有效的光二聚化。这项工作提供了金属卤化物促进[2 + 2]光二聚化的罕见例子，并为开发具有定制反应性的光显性材料建立了新的途径。

Photosalient [2 + 2] photodimerization in metal chloride-templated organic crystals†

Photo-salient metal chloride-templated organic–inorganic hybrid crystals incorporating (E)-1,2-bis(pyridin-4-yl)ethene (Ebpe) exhibited pronounced photo-salient effects, demonstrably jumping upon UV-induced [2 + 2] photodimerization. Detailed structural analysis reveals that the metal chloride component is an effective template, precisely aligning Ebpe molecules for efficient photodimerization. This work provides a rare example of a metal halide facilitating [2 + 2] photodimerization and establishes a new pathway for developing photosalient materials with tailored reactivity.
