Abstract:
The IR- and UV-Vis spectroscopic study of samarium-mesogenic 4-pentyl-4'-cyanobiphenyl low temperatures co-condensates was made in temperature range 90-300 K. Two labile complexes with different metal/ligand ratio of 1:2 and 1:1 were found. They were characterized by methods of IR- and UV-spectroscopy. The solid state transformation of complex Sm(5CB)2 to Sm(5CB) was shown to take place at 170-210 K. The kinetics of the process revealed a wide distribution of complex reactivity and of reaction activation energy.
