Abstracts

In this paper we present the results of dielectric measurements of liquid crystal (LC) 5*CB arranged in porous matrices with a pore diameter of 100 and 20 nm. We analyse the effect of the surface interactions on the dynamics of the molecules. The results are compared with the results for bulk 5*CB. The most important observation is the blocking of the phase transition of 5*CB into the solid phase in the matrix with pore diameter of 20 nm.
