Porphyrin-imide-fullerene triads

The lifetime of D+.C.A produced by the sequential electron transfer increases as the distance between D+ and A increases. Porphyrin-imide-fullerene triads have been synthesised (Figure 12.11), with the three components separated by nonreactive spacer molecules. 

The multi-step electron transfer process in namral photosynthesis has been utilized in the construction of various triads using porphyrin, metalloporphyrin, fullerene, and imide as basic components for harvesting solar energy as electrical energy and for photoreduction of water to get clean fuel hydrogen [6, 7]. Recently, tetrads, pentads and hexads have been constructed using porphyrin, fullerene, and a chromophoric unit as basic components for fast energy transfer process. 

So far, a variety of synthetic polychro-mophoric model systems, that is, triads, tetrads, pentads, and so on, have been studied in connection with photosynthesis and reported by several groups [70-88]. The electron-transport components, porphyrins, quinones, aromatic imides, and fullerenes are commonly employed by...
