■(porphyrin)和酞菁(phthalocyanine)具有相似的结构:一个16个原子的大环形π电子结构(以下简称16元环结构),早先Kuhn用一维的电子气态模型来近似16元环上的电子结构,得到了和实验所得的光谱位置、偏振、振动结构一致的结果,以后Schnabel等和Ahrens等做了推广并且假设16元环结构上的电子运动自成一个共轭体系和苯环上的电子是分开的。
Porphyrin and phthalocyanine have a similar structure: a 16-membered macrocyclic π-electron structure (hereinafter referred to as 16-membered ring structure). Previously Kuhn used a one-dimensional electron-gas model to approximate the Electronic structures were obtained and the experimental results were consistent with the spectral position, polarization and vibration structure. Schnabel et al. And Ahrens et al. Then generalized them and assumed that the electronic motion of the 16-membered ring structure became a conjugate system and a benzene ring Electronic is separate.
