Perylene bisimides (PBIs) are fascinating dyes with various potential applications. To study the effects of introducing a dibenzo‐fused structure to the perylene moiety, π‐extended PBI derivatives with a dibenzo‐fused structure at both of the a and f bonds were synthesized. The twisted structure was characterized by X‐ray crystal structure analysis. In the cyclic voltammograms, the dibenzo[a,f]‐fused
ylene双酰亚胺(PBI)是具有各种潜在应用的引人入胜的染料。为了研究在the部分上引入二苯并稠合结构的影响,合成了在a键和f键上都具有二苯并稠合结构的π扩展PBI衍生物。通过X射线晶体结构分析表征了扭曲的结构。在循环伏安图中,二苯并[一,˚F ] -融合PBI显示可逆的氧化波在少得多的正电位,相对于二苯并[一,Ô]融合的PBI衍生物。这些数据表明,与在每个萘部分(两个蒽核)上一个环的稠合相比,在构成并四苯核的萘部分的两侧上的两个环稠合有效地提高了HOMO水平。二苯并[ a,f ]-融合的PBI衍生物在735 nm处显示吸收带,肩带达到900 nm。
