摘　　要：A type of novel electrospun supramolecular hybrid microfibers comprising poly(9-(4-(octyloxy)-phenyl)-2,7-fluoren-9-ol)(PPFOH)and poly(A/-vinylcarbazole)(PVK)are successfully prepared for intriguing multi-color emission properties.The supramolecular tunable PPFOH aggregation in PVK matrix endows the complex with a smart energy transfer behavior to obtain the multi-color emissions.In stark contrast to PVK fibers,the emission color of PPFOH/PVK fibers with an efficient dispersion of PPFOH fluorophores at a proper dope ratio can be tuned in a wide spectrum of blue(0.1%),sky blue(0.5%),nearly white(1%),cyan(2%),green(5%)and yellow(10%).Besides,conductive behaviors of the microfiber were demonstrated in accompany with the increment of the doping ratio of PPFOH to PVK.Successful fabrication of polymer light-emitting diode(PLED)based on the blended electrospun fiber provided a further evidence of its excellent electrical property for potential applications in optoelectronic devices.
