Morphology controlled supramolecular assemblies via complexation between (5,10,15,20-tetrakisphenyl-porphine) zinc and 4,4′-bipyridine: from nanospheres to microrings†
Abstract
We synthesized (5,10,15,20-tetrakisphenyl-porphine) zinc (ZnTPP), and investigated its self-assembly behaviour with 4,4′-bipyridine (Bipy) via different self-assembly protocols. The self-assembly experiments were performed in organic solvents and on a carbon-coated copper grid, which gave well-defined nanospheres and microrings, respectively.
