A simple route to organic-inorganic (O/I) nano-objects with different morphologies through polymerization-induced block copolymer self-assembly is described. The synthetic strategy relies on the chain-extension of polyhedral oligomeric silsesquioxanes (POSS)-containing macro-CTA (PMAiBuPOSS(13) and PMAiBuPOSS(19)) with styrene at 120 degrees C in octane, a selective solvent of the POSS-containing block. The polymerization system was proven to afford a plethora of O/I nano-objects, such as spherical micelles, cylindrical micelles, and vesicles depending on the respective molar masses of the PMAiBuPOSS and polystyrene (PS) blocks. The cooling procedure was also proven to be a crucial step to generate particles with a unique morphology.
