S. Gromov et al., PHOTOCHROMIC IONOPHORES - SYNTHESIS, PHOTOINDUCED ISOMERIZATION AND CYCLOADDITION OF CROWN-ETHER STYRYL DYES, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 246, 1994, pp. 183-186
The synthesis and structure of crown ether styryl dyes representing a
novel class of dyes are considered. Data on photoisomerization and pho
toinduced 1,2-cycloaddition with formation of cyclobutane derivatives
are briefly analyzed.
