Abstract

Abstract: The homologous numbers (n and N)of the porphine and amino-substituted tetraphenylporphyrin derivatives were determined.The spectra and the structural parameters are related to the homologous factor(1/2), respectively.According to this relation a set of the homologous linear equations was obtained:Y=a+b(1/2)^2/N, r>0.98where a and b are constants, r is the relative coefficient.The red shift of λ_max is explained.Some linear rules are obtained.

Key words: Homologous number, Homologous factor, Amino-substituted tetraphenylporphyrin and its derivatives, HMO
