Abstract
Methods for producing dendrons of different generations with hydrophobic functional end-groups, and for producing polyurethanes with the side-chain dendrons are disclosed step-by-step. The dendron with hydrophobic functional end-groups in the polyurethane systems, and the honeycomb-like structure thin films are obtained by a breath-figure process. The structures of dendrons and dendritic side-chain polyurethanes are respectively expressed in the following and the end-groups (R) of the dendron are long alkyl chains or perfluoroalkyl derivatives.
