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。

The synthesis and pharmacological activity of isoindolo[1,2-b]quinazolin-12(10H)-ones and isoindolo[2,1-a]benzimidazoles related to batracylin are described. The acute toxicity of batracyclin has been associated with the formation of its N-acetyl metabolite which is a potent inducer of unscheduled DNA synthesis in rat hepatocytes. The desamino derivative and the 8-aza analog of batracylin retained
