Electro-optical behavior of fullerene-containing liquid-crystalline dendrimers in solutions

The synthesis of multifunctional materials performed by multicomponent single mols. of special chem. architecture is one of the modern trends in materials science. In the present work, malonate dendrimers have been used as matrix mols. for the synthesis of novel liq. cryst. (LC) materials with covalently linked fullerene C60 as addnl. functional component. Two purposes have been realized in the mol. design of novel LCs: 1) combination of typical mesogene compds. as the end groups with dendritic structure of the matrix mol., and 2) incorporation of fullerene to LC mols. Electrooptical Kerr effect and hydrodynamic methods have been utilized to study the dendritic samples with a variable fullerene position for examg. the influence of fullerene on the mol. properties of the original LC dendrimers. It was detected that substituted fullerene C60 reinforces the electrooptical effect of LC dendrimers and only slightly changes their size and mobility in soln. [on SciFinder(R)]
