eng	Synthesis and study of properties of push-pull chromophores with 1,3,5 triazine as an acceptor moiety	The main goal of this work was preparing a series of new push-pull chromophores with 1,3,5-triazine. Eight push pull chromophores (7 compounds have not been described in the literature yet) were prepared by Suzuki and Sonogashira cross-coupling and Knowenagel’s condensation. Every compound have 1,3,5-triazine as electron windrowing group, dimethylamino group as a donor of electron and they are connected by conjugate system which is built by 1,4 phenyle, ethenylene or ethynylene or a combination thereof. All chromophores were analyzed by 1H and 13C NMR, HR MS with MALDI, IR and for five compounds were measure RTG analysis. The properties of final chromophores were investigated by cyclic voltammetry, UV/Vis spectroscopy, differential scanning calorimetry, and by the semi empiric calculations. The prepared chromophores are soluble in commercial organic solvents, they have good thermal stability and fluorescence properties. These facts it is giving good probability to use chromophore in optoelectronic with wide applications.	Push-pull chromofor; 1,3,5-triazin; akceptor; cross-coupling
