Morphological Evolution of Self-Assembled Structures Induced by the Molecular Architecture of Supra-Amphiphiles.

摘要: A series of telechelic supramolecular amphiphiles [POSS–Azo8@(β-CD–PDMAEMA)1→8] was accomplished by orthogonally coupling the multiarm host polymer β-cyclodextrin–poly(dimethylaminoethyl methacrylate) (β-CD–PDMAEMA) with an octatelechelic guest molecule azobenzene modified-polyhedral oligomeric silsesquioxanes (POSS–Azo8) under different host–guest ratios. These possess a rigid core and flexible corona. Increasing coupled onto POSS made molecular architecture tend to be symmetrical spherical. POSS–Azo8@[β-CD–PDMAEMA]1→8 could self-assemble into diverse morphologies evolving from spherical micelles, wormlike branched aggregates bowl-shaped vesicles. Distinct traditional linear amphiphilic polymers, we discovered that self-assembly dominantly regulated their architectures instead hydrophilicity, which has also been verified using computer sim...
