| 英文摘要 | Two alternative copolymers of thieno[3,4b]pyrazine (TPZ) and triphenylamine (TPA) or phenylene (Ph), P(TPA-TPZ) and P(Ph-TPZ), were synthesized by Wittig-Horner polycondensation and characterized by (1)H NMR, elemental analysis, GPC, TGA, cyclic voltammetry, UV-Vis absorption, and photoluminescence (PL) spectroscopy. The polymers are soluble in common organic solvents and possess good thermal stability. Both of them shows strong solvato-chromism phenomenon when dissolved in different solvents. The fluorescence of the copolymer solutions is efficiently quenched upon the addition of Hg(2+), indicating that the two copolymers could be good Hg(2+) detectors. More interestingly, the copolymers show high selectivity for the Hg(2+) detection and P(TPA-TPZ) shows higher sensitivity and selectivity toward the Hg(2+) detection than P(Ph-TPZ) does in the presence of other competing metal ions. The results imply that the conjugated polymers (CPs) containing the thieno[3,4b]pyrazine moiety are promising materials for chemosensors. Copyright (C) 2009 John Wiley & Sons, Ltd. |
