Abstract: Chemical graph theory is the application of discrete mathematics to chemistry applied to model, physical and biological properties of chemical compounds. In this paper we establish Atom-Bond Connectivity Index ABC(G), Geometric Arithmetic Index GA(G), First and Second Zagreb Indices M1(G) and M2(G), Randic Index R(G), Sum Connectivity Index SCI(G), Harmonic Index H(G), Augmented Zagreb Index AZI(G), Forgotten Index F(G), Inverse Sum Indeg Index ISI(G), Hyper-Zagreb Index HM(G) for Phthalocyanine Tetrasulfonic Acid, Phthalocyanine Octacarboxylic Acid, Anthraquinone Cyanines, Phthalocyanine Porphyrin and zinc bis(1,4-didecylbenzo) bis(3,4-pyridoporphyrazine).
Keywords: Degree, Topological indices, Molecular graph.
