عنوان انگلیسی Bis-DCM Type Dyes: Convenient Method for Synthesis of 2-(2, 6-bis(4-(dialkylamino)styryl)-4H -pyran-4-ylidene) Malononitrile Derivatives
چکیده انگلیسی مقاله An efficient and convenient method for synthesis of 2,6-bis (4-(dialkylamino) styryl)-4H-pyran-4-one starting from 4- (dialkylamino) benzaldehyde with 2,6-dimethyl-4H-pyran-4-onein the presence of MeONa as the base was described. Additionally, preparation of novel compounds with bis-DCM-type skeleton for application in organic light-emitting diodes was developed via reaction of malononitrile as active methylene group with 2,6-bis (4-(dialkylamino) styryl) -4H-pyran-4-one derivatives. 1H and 13C NMR, FT-IR spectroscopy supported the predicted structure of the products. The UV-Vis absorption spectra of synthesis compound were measured in diluted dichloromethane solution. Maximum absorption (lmax) values differ from 460 to 496 nm, this absorption is due to π-π* transition.
