Abstract

A compound consists of a fractal-like, plain or organometallic array useful for energy storage devices. A dendrimer useful in the synthesis of the fractal-like compound includes a single ligating moiety bound to a surface of each quadrant of the dendrimer. A method of making metallo-based (macro) molecules includes the steps of combining monomers selected from the group consisting of bipyridal- and terpyridal-based ligands with connecting metals and self assembling macrocycles wherein the monomes are interconnected by the metals.

Claims
