摘要
以2-噻吩甲酰三氟丙酮(TTA)为第一配体,三苯基氧磷(TPPO)为第二配体,通过与稀土铕离子进行配位,制备Eu(TTA)_3(TPPO)_2发红光的配合物;同时采用静电纺丝技术以聚乙烯吡咯烷酮(PVP)为载体基质,与樟脑磺酸(CSA)掺杂的导电聚苯胺(PANI)及荧光配合物Eu(TTA)_3(TPPO)_2制备出了一种新型的荧光导电纳米纤维Eu(TTA)_3(TPPO)_2/PANI/PVP。用扫描电镜(SEM)、荧光光谱仪(FL)、宽频介电松驰谱仪对荧光导电纳米纤维的性能进行分析。结果显示,荧光导电纳米纤维具有优异的荧光性能及良好的导电功能。
Eu complexes were synthesized by linking TTA and TPPO as ligand up to Eu3＋ as functional light-e-mitting group. Then, ultrafine composite fibers Eu（TTA ） 3 （TPPO）2/PA N I /PV P , in which Eu complex and PANI act as model luminescence and conducting materials respectively and PVP acts as a supporting material, were successfully prepared via electro-spinning as luminescence and electrical conduction materials. The proper-ties of the novel luminescence conducting fiber were characterized by scanning electron microscope （SEM ） 9 broadband dielectric spectrometer, fluorospectrophotometer （FL）. The composite nanofibers have good conduc-ting properties and excellent luminescent property.
