Degree-based graph entropies quantify structural heterogeneity in molecular networks. However, a unified entropy treatment of polythiophene and its bipolaron counterpart, together with a direct assessment of descriptor redundancy, is still lacking. This study therefore derives cl...

This study presents a graph-theoretical and descriptive structure–property analysis of the linear \(\alpha\)-linked oligothiophenes bithiophene, terthiophene, quaterthiophene, sexithiophene, and octithiophene. From the common edge partition of their hydrogen-suppressed molecular...

In chemical graph theory, a topological descriptor is a numerical quantity that is based on the chemical structure of underlying chemical compound. Topological indices play an important role in chemical graph theory especially in the quantitative structure-property relationship (...
