Аннотация:A new LC dendrimer of the first generation with azobenzene terminal groups which forms an SmA mesophase over a wide temperature range was synthesized. The photooptical behavior of the dendrimer in a dilute solution and in him was compared. It was shown that the E-Z photoisomerization of azobenzene groups proceeds both in solution and film under UV irradiation. This process is reversible photochemically and thermally: irradiation with visible light (similar to 550 nm) and annealing lead to the inverse Z-E photoisomerization. The kinetics of the inverse thermal process was studied, and its activation energy was calculated.
