Liquid-crystalline carbosilane dendrimers of different molecular architecture with photochromic mesogenic and aliphatic terminal groups
A. I. Lysachkov, N. I. Boiko, E. A. Rebrov, A. M. Muzafarov, and V. P. Shibaev
Second-generation (G-2) liquid-crystalline carbosilane block and statistical dendrimers with aliphatic (decyl) and photochromic (azobenzene-containing) mesogenic terminal groups and a G-2 homo-dendrimer containing the same mesogenic terminal groups were synthesized for the first time. The influence of dendritic architecture on the phase behavior of the dendrimers and on photoinduced Z—E-isomerization of the azobenzene fragments in mesogenic terminal groups in dendrimer solutions are discussed.
