On February 2, 2006, Nishiyabu, Ryuhei; Anzenbacher, Pavel Jr. published an article.Recommanded Product: 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile The title of the article was 1,3-Indane-Based Chromogenic Calixpyrroles with Push-Pull Chromophores: Synthesis and Anion Sensing. And the article contained the following:
Knoevenagel condensation of 2-formyl-octamethylcalix[4]pyrrole with selected 1,3-indanedione derivatives yields calix[4]pyrrole anion sensors with push-pull chromophores displaying strong intramol. charge transfer. The push-pull feature results in augmented signal output as well as in dramatic changes in anion selectivity exemplified by a 50-fold increase in acetate vs. chloride selectivity compared to the parent calix[4]pyrrole. The experimental process involved the reaction of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile(cas: 2510-01-2).Recommanded Product: 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile
