title: Morphology-controlled self-assembly of an organic/inorganic hybrid porphyrin derivative containing polyhedral oligomeric silsesquioxane (POSS).
abstract: An organic/inorganic hybrid porphyrin derivative, namely, metal-free tetrakisphenyl porphyrin-polyhedral oligomeric silsesquioxanes (H2 TPP-POSS) was synthesized by azide-alkyne click chemistry. The self-assembly behavior of H2 TPP-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 H2 TPP-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 crescent-shaped micelles, spherical micelles, doughnut-shaped vesicles, and ordered square sheets, could form in solvents with different polarities.
