Sugiyama, Kazuo published the artcileSynthesis and properties of macromonomer having azobenzene moieties as a mesogenic group, Product Details of C23H28N2O4, the publication is Kinki Daigaku Kogakubu Kenkyu Hokoku (1988), 31-5, database is CAplus.
4-Methoxy-4′-(6-methacryloyloxyhexyloxy)azobenzene was telomerized radically in the presence of HSCH2CO2H to give a telomer which was treated with glycidyl methacrylate to give the title macromonomer. DSC and polarization microscopy showed that the telomer was a nematic liquid crystal. Photoreversible cis-trans isomerization of the telomer was studied.
Kinki Daigaku Kogakubu Kenkyu Hokoku published new progress about 135529-02-1. 135529-02-1 belongs to esters-buliding-blocks, auxiliary class azo,Alkenyl,Benzene,Ester,Ether, name is 6-(4-((4-Methoxyphenyl)diazenyl)phenoxy)hexyl methacrylate, and the molecular formula is C9H9NO, Product Details of C23H28N2O4.
