In this contribution, the high-yield preparation and optical properties of some donor-acceptor butadiene dyes, generated by coupling of different 1,1-diaryl-2-propyn-1-ols with indan-1,3-dione, are presented. The reactions, which involve the initial Meyer

Among other photoinitiating systems, aromatic ketone based compounds have been largely exploited as photoinitiators (PIs). However, none of these compounds efficiently absorb above 420 nm. The search of novel architectures of PIs for getting an important

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-ethylidene>-1,3-indandione.
