​Natural processes of photosynthesis have increasingly inspired the fabrication of nanostructured molecular materials with advanced light-harvesting and electron-transfer features. [1-4] In this context, supramolecular chemistry allows diverse and disparate molecular building blocks to be amalgamated into highly ordered architectures through the process of self-assembly. These mimic the key functions of the photosynthetic reaction center; light harvesting, charge separation, charge transport, energy transfer, and catalysis. [5,6] Porphyrinoids, the basic building block of chlorophylls, have emerged as an exceptional class of light harvesters and electron donors in such supramolecular electron donor-acceptor hybrids [7-10]. A variety of significant applications from solar cells, hydrogen production to medical applications have been reported.
