Abstract
Organic/inorganic urea/malonamide dendron-POSS nanohybrids with different generations of dendrons and peripheral groups were prepared. Chemical structures of the nanohybrids were characterized with FTIR, 1H NMR, molecular mass spectrometry, and elemental analysis. The nanohybrids exhibited better solubility in organic solvents as compared to their corresponding dendrons. Self-assembled layered dendron/POSS structures were observed for the nanohybrids with the low generation dendrons, as evidenced by TEM analysis. The nanohybrids also exhibited amphiphilic property because of the hydrophilicity of urea/malonamide dendrons. Moreover, the morphologies of the nanohybrids could be tailored via using various casting solvents.
