Abstract
Binary mixtures of nematic 5CB with some kind of non-mesomorphic solut es were found to cause the increase in nematic-isotropic transition te mperature, contrary to usually observed decrease. ''Unusual'' solutes found in this work all had active hydrogen which can act as hydrogen b ond donor. Admixing of methyl or ethyl substituted compounds of above solutes resulted in usual depression of transition temperature. ''Unus ual'' increase in clearing temperature were attributed to the hydrogen bonding interaction between 5CB and solutes. The thermal effects of h ydrogen bonding interaction between 5CB and various nonmesomorphic sol utes were studied in detail.
