eng	2,4-Distyryl and 2,4,6-tristyrylpyrimidines: Synthesis and Optical Properties	The design and synthesis of twenty new 2,4,6-tristyrylpyrimidines and three new 2,4- distyrylpyrimidines were described by combining Suzuki-Miyaura cross-coupling reaction and Knoevenagel condensation. This strategy enables the synthesis of compounds with different substituents on each arm and thus allows modification of their electron donating or withdrawing effects. Optical properties of final compounds were studied by UV-Vis absorption and emission spectroscopy as well as their electronic properties by DFT and TD-DFT calculations. The influence of electron-donating and electron-withdrawing groups on each arm and comparison of results with 4,6-distyrylpyrimidines analogs, previously prepared in our research group, are shown.	2,4-Distyrylpyrimidines; 2,4,6-tristyrylpyrimidines; Suzuki-Miyaura reaction and Knoevenagel condensation
