• Nanostar dendrimers
• Nullity
• Kekule structures
• Anti-Kekule number
• Atom-bond connectivity index
• Geometric-arithmetic index

In this paper we calculate the number of Kekule structures, anti-Kekule number and nullity of some families of nanostar dendrimers. In case when the nanostar dendrimer has no Kekule structure, we give the size of a maximum matching in it. Furthermore, we investigate the first and fourth version of atom-bond connectivity index and first and fifth version of geometric-arithmetic index for these nano-structures.
