Hybrid Nanostructures Using Light-Emitting Polymers:Synthesis,Characteristics,and Applications
1.Introduction Fine hybrid nanostructures such as coaxial type inorganic-organic nanowires (NWs) and core shell nanoparticles (NPs) have been intensively studied because of the improvement and control of the intrinsic properties through the hetero-junction structure of different materials1. The nanostructured metals can be used to improve the light emission efficiency of light emitting materials through a surface plasmon resonance (SPR) coupling2. Π-Conjugated polymers have been applied to optoelectronic devices. Various nanostructures using π-conjugated polymers have been synthesized through the electrochemical or chemical polymerization methods3. They have been applied to biological and chemical sensors, nanotip emitters, electrochromic devices, etc. Herein, fine hybrid nanotubes (NTs), NWs, and NPs of light emitting polymers, polythiophene (PTh), poly (3-methylthiophene) (P3MT), or MEH-PPV, with inorganic materials were fabricated. The laser confocal microscope (LCM) PL intensity of the single strand of the PTh/metal hybrid NTs increased up to~1004. The nanoscale LCM PL intensities of P3MT based-hybrid NTs remarkably increased up to~350 times as the doping levels of the P3MT NTs increased5. For the MEH-PPV NPs, the increase of the LCM PL efficiency after the attachment of the Au NPs was observed. We investigated the photo-responsive I-V, nano-junction effect, and bio-sensing characteristics using the single strand of the hybrid nanostructures.
