2-(Anthracen-9-ylmethylene)malononitrile (cas: 55490-87-4) belongs to nitriles. The R-C-N bond angle in and nitrile is 180° which give a nitrile functional group a linear shape. Both the carbon and the nitrogen are sp hydridized which leaves them both with two p orbitals which overlap to form the two π bond in the triple bond. Nitriles are susceptible to hydrogenation over diverse metal catalysts. The reaction can afford either the primary amine (RCH2NH2) or the tertiary amine ((RCH2)3N), depending on conditions.Application of 55490-87-4

Density function theory study on anthracene substituted by dicyanovinyl in different positions was written by Zhang, Jinglai;Miao, Tifang;Wang, Hua;Tian, Anmin. And the article was included in Huaxue Tongbao in 2003.Application of 55490-87-4 This article mentions the following:

Results of RHF(RHF) and d. function theory(DFT) calculations are reported for 2-dicyanovinyl anthracene(2-DCVA) and 9-dicyanovinyl anthracene(9-DCVA) at B3LYP/6-311+G(d,p)//RHF/6-31G(d,p) level. The equilibrium geometries of 2-DCVA and 9-DCVA have been optimized and the harmonic vibrational frequencies have been calculated The calculating results show that the ground state of 9-DCVA is higher than that of 2-DCVA in total energy. Having revolved angles between anthracene and dicyanovinyl from -180.0° to 180.0°, their potential energy curves are obtained to find their equilibrium geometries, The results show that there are two different stable geometries in energy and a transition geometry for 2-DCVA while there are a stable geometry and two transition geometries for 9-DCVA, the structure of 2-DCVA is more planar than 9-DCVA. At PM3/CIS level, their electronic spectrum were calculated and the vertical excitation energies and corresponding oscillator strengths from the ground states to the excited states are obtained. These results are in good agreement with the results obtained from experiment In the experiment, the researchers used many compounds, for example, 2-(Anthracen-9-ylmethylene)malononitrile (cas: 55490-87-4Application of 55490-87-4).
