Porphyrins analogues with fullerenes

Figure 5.56 Schematic illustrating the self-assembled multilayers of sodium 3-mercaptoethane-sulfonate (layer 1 ), hexacationic homooxacalix[3]arene-fullerene (2 1) complex (layer 2 ), with either the anionic porphyrin polymer ( 3 ) or its zinc porphyrin analogue ( 4 ) forming the third layer.

Condensing racemic l,2-methano[70]fullerene-71-carboxylic acid obtained by hydrolysis of its tert-butyl ester (( )-260, Scheme 1.25),243 with an amino derivative of zinc tetraphenylporphyrin, Imahori, Yamazaki, Sakata, and coworkers synthesized a C7o-containing dyad.355,446 Comparison with the C60-analogue showed that photoinduced electron transfer from the singlet excited Zn-porphyrin to the fullerene is faster in the C70 derivative.
