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-Triphenylimidazole (TPI) and 1,3,5-triphenylpyrazoline (TPP) are small organic molecules with strong photoluminescence and electroluminescence properties. TPI is the energy transfer Donor, TPP as energy transfer receptor, using TPP-doped TPI nanotubes prepared by re-precipitation method. The doped nanotubes formed by TPI and TPP can efficiently transfer energy, and the incorporation of a small amount of TPP can significantly quench the fluorescence of TPI. With the increase of the amount of TPP, the fluorescence lifetime of the TPI emission at 374 nm was significantly shortened, indicating that the fluorescence resonance energy transfer mechanism was mainly used between TPI and TPP.
