And the article contained the following:

Disperse dyes derived from 1-indanylidenemalononitrile and aromatic aldehydes were prepared and characterized. The purity of the dyes was checked by TLC and elemental anal.; the structures were confirmed by 1H and 13C NMR spectra. The relationships among dye structures and absorption characteristics and solvent polarity effects were investigated. The full optimized geometry was computed by the AM1 method and the theor. characteristics of electronic transitions were studied by PPP-MO, CNDO/S, and INDO/S procedures. Due to possible application of the dyes to polyester fiber, the coloristic characteristics were determined as well. The experimental process involved the reaction of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile(cas: 2510-01-2).Synthetic Route of 2510-01-2

Estrada, Leandro A.; Frances-Monerris, Antonio; Schapiro, Igor; Olivucci, Massimo; Roca-Sanjuan, Daniel published an article in 2016, the title of the article was Mechanism of excited state deactivation of indan-1-ylidene and fluoren-9-ylidene malononitriles.Reference of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile And the article contains the following content:

Herein, we report complementary computational and exptl. evidence supporting the existence, for indan-1-ylidene malononitrile and fluoren-9-ylidene malononitrile, of a non-radiative decay channel involving double bond isomerization motion. The results of UV-Vis transient absorption spectroscopy highlight that the decay takes place within hundreds of picoseconds. In order to understand the related mol. mechanism, photochem. reaction paths were computed by employing multiconfigurational quantum chem. The results indicate that the excited state deactivation occurs via concerted double bond twisting of the dicyanovinyl (DCV) unit coupled with a pyramidalization of its substituted carbon. It is also shown that the observed differences in the excited state lifetimes when passing from indan-1-ylidene malononitrile to fluoren-9-ylidene are associated with the change in the topog. of the conical intersection driving the decay from intermediate to sloped, resp.

On April 21, 1999, Konstantinova, Lidia S.; Rakitin, Oleg A.; Rees, Charles W.; Souvorova, Ljudmila I.; Torroba, Tomas published an article.Synthetic Route of 2510-01-2 The title of the article was One-pot synthesis of indeno-1,2-thiazines, -[1,2]dithioles and thiophenes; new liquid crystalline materials. And the article contained the following:

In a search for further examples of a new type of discotic liquid crystal, the authors have examined the reactions of S2Cl2 in the presence of a chlorinating agent (NCS) and a base (Hunig’s base or DABCO), mostly in THF, with cyclopent-1-enylacetic acid (I), inden-3-ylacetic acid (II) and its nitrile (III) and 1-(dicyanomethylene)indane (IV). The cyclopentene acid I gives purple crystals of the trichlorocyclopenta[1,2]dithiole ester, the product of heterocyclic ring formation, chlorination and dehydrochlorination and, unexpectedly, conversion of the acid in THF into its 4-chlorobutyl ester. Indenylacetic acid II gives methyleneindenes, the tricyclic 1,2-dithiolone V and the deep purple thiophene VI. Indenylacetonitrile III gives E-1-(伪-chloro-伪-cyanomethylene)indane and E- and Z-1-(伪-chloro-伪-cyanomethylene)-2,3-dichloroindene and Z-2-chloro-1-(伪-cyanomethylene)indane, depending upon the precise reaction conditions. Dicyanomethylene indane IV gives 1-(dicyanomethylene)-2,3-dichloroindene (VII) and the red, thermochromic 3,9-dichloro-4-cyanoindeno[1,2-e]-1,2-thiazine; the analogous cyano-ester gives the corresponding products. On melting, crystals of VI and VII are strongly birefringent. Mechanisms are proposed for the new transformations. The experimental process involved the reaction of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile(cas: 2510-01-2).Synthetic Route of 2510-01-2
