2-(2-(tert-Butyl)-6-methyl-4H-pyran-4-ylidene)malononitrile（Cat No.:L014605）is a highly conjugated organic molecule featuring a substituted pyran ring with a tert-butyl group at the 2-position, a methyl group at the 6-position, and a malononitrile moiety at the 4-position via a ylidene linkage. This structure offers strong electron-donating and electron-withdrawing groups, creating a push–pull system ideal for optoelectronic applications. It is commonly used in the development of organic semiconductors, nonlinear optical materials, and dye-sensitized solar cells. The compound’s extended conjugation and tunable properties make it valuable in advanced material science research.
