Porphyrazines () are porphyrinoids, which are macro-cyclic compounds made up of four in-dole rings.has various potential and practical uses in health and technology due to their distinctive optical and electrochemical characteristics. Topological descriptors are numerical values given to molecular structures that may be used to predict specific physical characteristics. In this work, we have investigated topological features of the porphyrazine and tetrakis porphyrazine structure based on degree. We have calculated the closed forms of the Zagreb, Randic, geometric-arithmetic, harmonic, augmented and atom-bond connectivity (ABC) indices of the porphyrazine and tetrakis porphyrazine structures. The present research would be beneficial for understanding the structure's biological and chemical activity.

Computation of degree-based topological indices for porphyrazine and tetrakis porphyrazine
