Paper Abstract

In this works, synthesis and evaluation of the luminescence properties of novel polythiophenes derivatives derived of 3- alkylthiophenes (alkyl=hexyl, octyl) and thiophenes functionalized with a NLO chromophore: 2-[Ethyl[4-[2-(4- nitrophenyl)ethenyl]phenyl]amino]ethanol are reported. The optical response of copolymers films obtained by spin coating technique when they were excited optically was analyzed. The fluorescence signals measured to about 650 nm when the copolymers were excited at 488 nm (blue light) were studied to different excitation powers. The optical response of the copolymers films shows a change ratio of around 6%/mW. The evaluations of photoluminescence properties of conjugated polythiophenes are important due to their potential applications in light-emitting diodes (LEDs), solar cells and chemical sensors.
