Nanoscale Organization of a Phthalocyanine−Fullerene System: Remarkable Stabilization of Charges in Photoactive 1-D Nanotubules

Abstract

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.
