制备了苯甲酸辛酯取代的[12]DBA(C8[12]DBA)作为有机分子玻璃材料。即使具有[12]DBA的中心大的、平面的pi单元，这通常有利于形成结晶/液晶状态，但由于其在[12]DBA单元之间的小分子间pi接触和末端苯甲酸酯单元周围的扭曲几何结构，该化合物形成了热稳定的玻璃态。C8[12]DBA在玻璃态下表现出独特的介电异常和孤立的荧光性质。
We prepared octylbenzoate-substituted [12]DBA (C8[12]DBA) as an organic molecular glass material. Even with a central large, planar pi unit of [12]DBA, which is generally advantageous for the formation of a crystalline/liquid crystalline state, this compound formed a thermally stable glass state due to its small intermolecular pi contact between [12]DBA units and twisted geometries around the terminal benzoate units. C8[12]DBA showed a unique dielectric anomaly and isolated fluorescence properties in the glass state.
