Cyanuric chloride was used as raw material to synthesize 2-chloro-4,6-bisbiphenyl-1,3,5-triazine(Ⅳ) successfully via Grignard reaction and Friedel-Craft reaction.Three 2,4-bisbiphenyl-6-(2-hydroxyl-4-alkoxyl)-1,3,5- triazine compounds(Ⅴ1~3) were synthesized by compound Ⅳ and bromoalkane in the presence of K2CO3.The structures of compounds Ⅴ1~3 were characterized by FTIR,MS and 1HNMR. Thermal stability,ultraviolet absorption and light stability of compounds Ⅴ1~3 were tested by TGA and UV-vis.T5 of compounds Ⅴ1~3 was raised 40～60℃ related to UV-1577．Maximum molar absorption coefficient(εmax) of compounds Ⅴ1~3 was 79448.28 L/（molcm）(max=318.5 nm),80873.51 L/（molcm）(max=319 nm),76774.7 L/（molcm）(max=319 nm) respectively.
