Porphyrin-phthalocyanine nanorods (P-PcNR) formed by electrostatic self-assembly

Abstract

Porphyrin-Phthalocyanine nanorods had been formed by electrostatic self-assembly of two oppositely charged complexes. The negatively charged complex was meso-tetra-4-phenylsulfonated porphyrin (H₂TPPS₄⁴) and the two positively charged complex were tin and indium complexes of tetra {2,(3)-(2-mercaptopyridine) phthalocyaninato}(MTSPyPc). The transmission electron microscope (TEM) images of the colloid suspension
of the aggregate confirmed formation of nanorods while their electron spectra showed that the molecules formed J-aggregation.
