A series of push-pull butadiene dyes (new merocyanine dyes) containing 3,6-bis(dimethylamino)fluorenylidene, thioxanthenylidene, or 10-(9-xanthenylidene)-9(10H)-anthrylidene chromophore was easily synthesized from the corresponding 1,1-diaryl-2-propyn-1-ol systems.Their absorption spectral properties were examined and the relationship between their light absorption properties and chemical structures is discussed in comparison with the results from PPP-SCF-CI-MO calculations.The influence of the solvent polarity on the 1/λmax (= wave number)-values of the dyes was investigated, and the solvatochromic nature compared with the known solvent polarity parameters such as ET30, Z, κR, ?*azo on 2-<2-<3,6-bis(dimethylamino)fluorenylidene>ethylidene>-1,3-indandione.
