Subject : Novel dyes derived from hydrazones. Part 2: synthesis and characterizations of Nmethyl-4 
Document Language : English 
Abstract : Novel tricyanovinyl derived from N-methylhydrazones have been prepared by the reaction of tetracyanoethylene and N-methylbenzyijdenehydrazone and these dyes showed absorption in the region of 500 nm. The dyes showed pronounced solvatochromic effects as the solvents’ polarity increased. Some of the new dyes were studied to show their aggregation properties in Solution as the concentration changed. Most of the dyes studied showed change in the absorption spectrum and hence the position of the maximum absorption bands. The thermal stability of some of the prepared dyes was studied in poly(methyl methacrylate) film at 80 °C; the substitution on the aromatic aldehydes showed some improvement of the thermal stability of the dyes
