2-butyne-1,4-diol () is used as a divergent ditopic template that directs -1,2-bis (pyridyl) ethylene (, where = ' = 3 or 4) to undergo an intermolecular [2 + 2] photodimerization in the solid state. The components of cocrystals [()·()] and [()·()] form 1D hydrogen-bonded polymers with assembled as infinite parallel stacks. The alkenes undergo [2 + 2] photocycloadditions to form -tetrakis (-pyridyl) cyclobutane (where = 3 or 4). We demonstrate that the reactive solid involving exhibits supramolecular catalysis.
2-丁炔-1,4-二醇（）可用作发散双位点模板，引导 1,2-双（吡啶基）乙烯（，其中 = '= 3 或 4）在固态中进行分子间 [2 + 2] 光二聚反应。共晶[()]·()]和[()]·()]的组成部分形成 1D 氢键聚合物，其中 组装为无限平行堆叠。烯烃发生 [2 + 2] 光环加成反应，形成 -四（-吡啶基）环丁烷（其中 = 3 或 4）。我们证明了涉及的反应性固体表现出超分子催化作用。
