摘要
Novel fullerene C-60 containing liquid crystalline dendrimers and hemidendrimers have been characterized by the method of electro-optical Kerr effect and determination of the permanent dipole moment, sensitive to the molecular polar ordering and anisotropy of polarizability, and by hydrodynamic methods in solution. An influence of the covalently bonded fullerene on the polarity. electro-optical, and viscometric properties of fullerene derivatives have been detected, analyzed, and concluded that fullerene produces a change in the original ordering in dendritic molecules, which mainly resulted in correction of the shape asymmetry of these molecules as a whole.
