Electrophoretic migration imaging process was written by VanAllan, J. A.;Rossi, L. J.;Bloom, M. S.;Regan, M. T.;Wright, H. E.;Kaukeinen, J. Y.. And the article was included in Research Disclosure in 1978.Product Details of 55490-87-4 This article mentions the following:
Twenty-five photosensitive compounds having the general structure Z(CH:CRR1)n where Z is phenylene, naphthylene, anthracenyl, anthracenediyl, or dibenzothiendiyl, n = 1 or 2, and R and R1 are H, CN, alkylsulfonyl, alkylcarbonyl, arylcarbamoyl, cyanoaryl, arylcarbonyl, or together form an substituted or unsubstituted ring are described for use in electrophoretic imaging. Thus, a dispersion (containing Isopar G 2.2, Solvesso 100 1.3, Piccotex 100 1.4, and lauryl methacrylate-Li methacrylate-methacrylic acid-vinyltoluene polymer 0.1 g) 5 and 5,5′-(9,10-anthracenediyldimethylidyne)bis[3,4-di(p-nitrophenyl)furan-2-one] 0.045 g were milled with stainless steel balls 12 g for 3 h and then evaluated to show a useful level of photosensitivity. In the experiment, the researchers used many compounds, for example, 2-(Anthracen-9-ylmethylene)malononitrile (cas: 55490-87-4Product Details of 55490-87-4).
2-(Anthracen-9-ylmethylene)malononitrile (cas: 55490-87-4) belongs to nitriles. Trimerization of aromatic nitriles requires harsh reaction conditions, high temperatures, long reaction times, and pressure. In addition, Nitriles can react with alkynes, which leads to an increase in carbon chain length (carbocyanation).Product Details of 55490-87-4
