Abstract: fluorescent conjugated polymer nanowire array was fabricated based on two 1,3,5-trinitrotoluene（TNT）sensitive polymers——Triphenylamine-co-para-biphenyene vinylene（TPA-PBPV）and Triphenylamine-co-para-phenylene vinylene（TPA-PPV）with porous anodic aluminum（PAA）template.Compared with that of spin-coated film,the emission maxima of both TPA-PBPV and TPA-PPV were blueshifted from 485 to 455 nm and from 495 to 475 nm respectively.The blueshifted emission suggests the polymer nanowire array is effective for preventing the energy trap.Therefore,it is a promising technique for further enhancing the TNT sensory performance.
