本文研究了热稳定的萘苯并咪唑和萘酰亚胺的微波辅助合成、光物理和电化学性质。萘苯并咪唑的微波辅助合成比传统的热合成提供更高的产率。萘苯并咪唑和萘酰亚胺的比较光物理性质表明,给电子基团与萘酰亚胺部分的共轭增加了荧光量子产率。还使用萘二甲酰亚胺和萘苯并咪唑的 Lippert-Mataga 方程研究了荧光团-溶剂相互作用。由于芳香性增加,萘苯并咪唑的热稳定性优于萘酰亚胺。实验性的 E LUMO发现萘苯并咪唑的水平在 3.15 和 3.28 eV 之间。因此,由锚定基团组成的萘苯并咪唑衍生物是有机染料敏化太阳能电池中很有前景的材料。

A series of new benzimidazolederivatives were synthesized by the solid‐state condensation and direct sublimation (SSC‐DS) method and their physicalproperties were investigated. The reaction yields and product stability were significantly affected by the identity of the diamine and anhydride substituents. On the other hand, the substituents of the benzimidazole ring allowed fine tuning of the emission
通过固态缩合和直接升华(SSC-DS)方法合成了一系列新的苯并咪唑衍生物,并研究了它们的物理性质。二胺和酸酐取代基的身份显着影响反应产率和产物稳定性。另一方面,苯并咪唑环的取代基可以对发射最大值,荧光量子产率和氧化还原电位进行微调。通过循环伏安法在氧化铟锡(ITO)上的膜中估算HOMO-LUMO的水平,并将其与其他方法获得的值进行比较。所描述的苯并咪唑显示出高结晶度,这归因于高平面度以及碳与杂原子之间的相互作用。这些化合物在有机场效应晶体管(OFET)中表现出n型半导体行为。-2 cm 2 V -1 s -1。
