A Combined Experimental and Theoretical Approach toward the Development of Optimized Luminescent Carbostyrils
Strohmeier, Gernot A.,Fabian, Walter M. F.,Uray, Georg
, p. 215 - 226 (2007/10/03)
The synthesis and photophysical data of new carbostyrils (quinoline-2(1H)-ones) with the longest hitherto observed absorption- and emission wavelengths are described. Introduction of 6-amino, 7-MeO, and 4-(CF3) substituents enabled us to rise the absorption and fluorescence maxima up to 414 and 557 nm, respectively. Supported by semi-empirical and ab initio calculations, the 6,7-(1,4-diazine)-fused carbostyril 23b displayed absorption maxima at up to 440 nm, with quantum yields of up to 0.9 and large Stokes shifts (> 100 nm), comparable to the best coumarin chromophores known. The new fluorophore is neither pH-sensitive between pH 6 and 10 nor susceptible to O2 quenching. At pH 3, the emitted light appears greenish-white, which arises from three different stages of protonation.
Amination of Nitroarenes with Sulfenamides via Vicarious Nucleophilic Substitution of Hydrogen
Makosza, Mieczyslaw,Bialecki, Maciej
