| Abstract: | Poly(arylene ethynylene)s,P1 and P2 containing 1,3,5-triazine and chalcone unites respectively,were synthesized by Sonogashira coupling reaction.These polymers exhibited good solubility in common organic solvents,such as dichloromethane,chloroform,and tetrahydrofuran.The molecular weight M_w of P1 was 6390 with polydispersity(PDI) being 2.33 and that of P2 was 6870 with polydispersity(PDI) being 1.85 characterized by GPC.The photophysical properties were analyzed by solution and solid state photoluminescence spectroscopy.P1 emitted blue fluorescence at around 441 nm in CH_2Cl_2 or THF solutions under UV excitation.The photoluminescence behavior of P2 was dependent on the solvent,with green emitting light at around 550 in CH_2Cl_2 solution and 500 nm in THF solution.Powder photoluminescence spectra of P1 and P2 showed that the peak wavelengths respectively shifted to 530 and 605 nm. |
