We examined the solvent effect on the electronic absorption and infrared absorption spectra of a push-pull molecule fabricated by connecting donor and acceptor segments linked with a quinoid bridge, {4-[4,5-bis(methylsulfanyl)-1,3-dithiol-2-ylidene]cyclohexa-2,5-dien-1-ylidene}malononitrile (BMDCM), in liquid solutions. A BMDCM molecule represented by...
