通过电子吸收、MCD和CI计算，研究了一系列低对称性的无金属四氮杂卟啉（TAP）衍生物，即单苯并取代（1H2）、邻二苯并取代（2AdH2）、反二苯并取代（2OpH2）和三苯并取代（3H2）TAP衍生物，证明了1H2和3H2中存在两种质子转移互变异构体.
A series of low-symmetry metal-free tetraazaporphyrin (TAP) derivatives, i.e. monobenzo-substituted (1H2), adjacently dibenzo-substituted (2AdH2), oppositely dibenzo-substituted (2OpH2), and tribenzo-substituted (3H2) TAP derivatives, has been investigated by the combined use of electronic absorption, MCD, and CI calculations, proving the existence of two prototropic tautomers in 1H2 and 3H2.
