摘　　要：2,4,5-三苯基咪唑(TPI)和1,3,5-三苯基吡唑啉(TPP)是具有强光致发光和电致发光性能的有机小分子,以TPI为能量传递给体,TPP为能量传递受体,采用再沉淀法制备出TPP掺杂的TPI纳米管。TPI和TPP形成的掺杂纳米管能够发生高效的能量传递,掺入很少的TPP就能对TPI的荧光造成明显淬灭。随着TPP掺入量的增加,能量传递给体TPI在374nm发射光的荧光寿命显著变短,表明TPI和TPP之间主要采用荧光共振能量传递机制。2,4,5-three phenyl imidazo（TPI）and 1,3,5-three phenyl pyrazoline（TPP）have the properties of photoluminescence and electroluminescence.With TPI as the energy donor and TPP as energy acceptor,the doping nanotubes of TPP and TPI were prepared by the precipitation method.The doping nanotubes have the properties of efficient energy transfer,doping very little TPP into the TPI nanotubes can cause significant TPI fluorescence quenching.With increasing the TPP,the fluorescence lifetime of TPI in the 374nm emission was shortened,which indicated that fluorescence resonance energy transfer occurs between TPI and TPP.
