- W2371036209 abstract "Poly(2,5-dipentyloxyphenylene ethynylene carbazyl)(P) was synthesized with 2,5-dimethoxy-1,4-diethynylbenzene and 3,6-diiodo-9-pentylcarbazole by Pd-catalyzed Sonogashira coupling reaction.The fluorescence quenched properties of P was influenced obviously by the structure and relative position of the substituting groups of nitrobenzene derivates.For the para-substituting nitrobenzene,the fluorescence quenching efficiency of quenchers increased with the increase of electron repulsion capability of the para-substituting group.And the fluorescence quenching efficiency reduced according to the sequence of o-NA,p-NA and m-NA under the same conditions due to the different electron withdrawing conjugated effect and inductive effect between amino-and nitro-group in nitroaniline isomers.Further study exhibits that the fluorescence quenching efficiency increases nonlinearly with the concentration of the quenchers." @default.
