An organic/inorganic hybrid porphyrin derivative, namely, metal-free tetrakisphenyl porphyrin-polyhedral oligomeric silsesquioxanes (H2TPP-POSS) was synthesized by azide-alkyne click chemistry. The self-assembly behavior of H2TPP-POSS was systematically studied in CHCl3, at different concentrations and in solvents with different polarities. Novel nanovesicles could be obtained through the self-assembly of H2TPP-POSS in CHCl3, at a concentration lower than 10(-4) M. Diffuse microrods formed at a concentration higher than 10(-4)M. Additionally, the polarity of the solvent also greatly influenced the assembled morphologies, and a series of assembled morphologies, including crescentshaped micelles, spherical micelles, doughnut-shaped vesicles, and ordered square sheets, could form in solvents with different polarities.
