In this study, we report on the synthesis of new organic fluorophores containing either the p-phenylene or the benzodithiophene cyclic nucleus connected to thiophene units via triple bonds and carbonyl group, and on their application for the fabrication of luminescent solar concentrators (LSCs). Their optical properties were evaluated. Independent of the core, dyes containing the CO-thiophene residues seem to be the most promising for LSCs applications. In fact, carbonyl groups slightly enhance the quantum yield but significantly increase the red-shift of the emission so that the superimposition between the absorbance spectrum and the emission one is diminished. In the case of the benzodithiophene center, light emission in the yellow-red portion of the spectrum is achieved. The latter dye is then selected for tests in a poly(Me methacrylate) (PMMA) matrix. It showed good compatibility and homogenous distribution, no auto-absorption phenomena, and optical efficiencies of about 8% at 1 weight %, i.e. comparable with those PMMA/Lumogen Red films in the same range of concentration
