Abstract: Let G be a molecular graph, the eccentric connectivity index of G is defined as xc(G) = åu ÎV(G)deg(u)·ecc(u), where deg(u) denotes the degree of vertex u and ecc(u) is the largest distance between u and any other vertex v of G, namely, eccentricity of u. In this study, we present exact expressions for the eccentric connectivity index of two inﬁnite classes of nanostar dendrimers.
Keywords: eccentric connectivity index, nanostar dendrimers, topological index, eccentricity
