Asiri, Abdullah Mohamed published an article in 1999, the title of the article was Synthesis, characterizations and absorption spectral studies of novel 2-arylidene-1-dicyanomethyleneindane dyes.Product Details of 2510-01-2 And the article contains the following content:
The synthesis and the absorption properties of methine dyes formed by Knoevenagel condensation of aromatic aldehydes with 1-(dicyanomethylene)indan afforded a novel series of dyes absorbing in the region of 490-593 nm. The substituents on the aromatic aldehyde have remarkable effects on the visible absorption maxima of the new dyes. Increasing the solvent polarity had pronounced effects on the absorption maxima. The experimental process involved the reaction of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile(cas: 2510-01-2).Product Details of 2510-01-2
