The systemic analysis of photosynthesis led in the late 1980s to the bioinspired concept of "integrated modular assembly" as a simple basis for constructing molecular devices, fashioned of any nanoscale material capable of holding the active elements at fixed distances, which can transform photonic energy into vectorial electron transfer. We describe our initial efforts in the de novo design of phthalocyanine-based charge separation domains which can be modularly attached via molecular Lego to other designed or natural protein domains and act as centers for light activated electron extraction and/or injection. We are coupling these materials to novel metamaterial electrodes which hold great promise as solid-state light harvesting and distribution materials in multi-junction biofuel-generating solar energy nanodevices.
