Nanoscale organization of a phthalocyanine-fullerene system:: Remarkable stabilization of charges in photoactive 1-D nanotubules

Induction of self-organization between zinc phthalocyanine (ZnPc) and C60 moieties in a novel amphiphilic ZnPc-C60 salt results in uniformly nanostructured 1-D nanotubules. Their photoreactivity, in terms of ultrafast charge separation (i.e., ∼1012 s-1) and ultraslow charge recombination (i.e., ∼103 s-1), is remarkable. In addition, the observed ZnPc•+-C60•- lifetime of 1.4 ms implies, relative to that of the monomeric ZnPc-C60 (∼3 ns), an impressive stabilization of 6 orders of magnitude.
