cross-coupling reaction of the corresponding 6-alkyl-2-bromoazulenes. The redox behavior of 3a, 3b, and 3d including that of their 6-octyl and 6-hexadecyl derivatives 3c (n=8) and 3e (n=16), the synthesis was reported previously, was studied in detail by voltammetric and electrochromic analyses. As the results, amphoteric redox properties with a significant color change were revealed by the nPA homologous
六个新的6-烷基-2-苯基杂氮烯(n PA,n为6-烷基链中的碳原子数)同源系列3a(n = 4),3b(n = 6)和3d(n Pd(PPh 3)4催化了相应的6-烷基-2-溴氮杂唑的Suzuki-Miyaura交叉偶联反应,合成了= 10),预期将近晶E(SmE)相显示为低于熔融状态的中间相。3a,3b和3d的氧化还原行为,包括其6-辛基和6-十六烷基衍生物3c(n= 8)和3e(n = 16),先前已报道了合成方法,并通过伏安法和电致变色分析对其进行了详细研究。结果,n PA同源系列3a – e揭示了具有明显颜色变化的两性氧化还原特性,这将被分子材料的器件制造应用所吸引。
