2-arylbenzotriazoles related to the UV absorber Tinuvin P have been studied. Moreover, besides those bearing a 2′-hydroxy substituent, known to experience ESIPT (Excited-State Intramolecular Proton Transfer), we have also prepared three compounds having another ortho-hydroxy group at position 6′. The X-ray molecular structures of five key representatives have been determined and some important features related to their
已经研究了总共19种与紫外线吸收剂Tinuvin P有关的2-芳基苯并三唑。此外,除了已知经历ESIPT(激发态分子内质子转移)的带有2'-羟基取代基的那些化合物外,我们还制备了三种在6'位具有另一个邻羟基的化合物。确定了五个主要代表的X射线分子结构,并在溶液和固态NMR以及B3LYP / 6-311 ++ G(d,p)计算的基础上,讨论了与它们的行为相关的一些重要特征结果。
