On July 31, 2009, Li, Xiaochuan; Kim, Sung-Hoon; Kun, Jun; Son, Young-A. published an article.Electric Literature of 2510-01-2 The title of the article was Synthesis and Optical Properties of (A)n-π-(Ph)3N Type Dyes. And the article contained the following:
Two new (A)n-π-(Ph)3N type dyes were designed, synthesized and characterized. The optical properties and structures of them were studied, including UV-visible spectroscopy, photo-luminescence spectroscopy. The geometric structures of them were calculated theor. based on the DFT level using BLYP/GGA basis set, the HOMO/LOMO levels were also measured and calculated The experimental process involved the reaction of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile(cas: 2510-01-2).Electric Literature of 2510-01-2
The Article related to dye synthesis optical property, Optical, Electron, and Mass Spectroscopy and Other Related Properties: Optical Properties (Linear) and other aspects.Electric Literature of 2510-01-2
