摘 要:The poly(2,5-dipentyloxy-para-phenylene ethynylene)(P) was synthesized by Pd-catalyzed Sonogashira coupling *** to causing energy transfer between the nitrobenzene’s quenchers and the polymer chains through the charge-transfer interaction,the fluorescence quenched properties of P varied obviously with the para-substituting group’s structure in the nitrobenzene *** fluorescence quenching efficiency of quenchers improved with increasing of electron repulsion capability of the para-substituting *** fluorescence quenching efficiency increased nonlinearly with the concentration of the quenchers and had,however,no relation with the quenching time.
