Abstract

A head-to-head photodimerization of a β-substituted thiophene stacked face-to-face in the solid state using a ditopic hydrogen-bond-donor template is reported. The face-to-face stacking is attributed to contributions of intertemplate forces, which contrasts an assembly wherein the same thiophenes stack edge-to-face yet maintain a discrete hydrogen-bonded structure.

摘要

报道了一种使用双位氢键给体模板在固态下β-取代噻吩面对面的直接光二聚反应。面对面的堆积归因于模板间力的贡献，这与相同的噻吩堆积边缘对边缘但保持离散氢键结构的组装形成对比。
