Hybrid of Conjugated Polymers with Incorporation of Metal Oxide Nanocomposites for Improving Optoelectronic Properties
نویسندگان
چکیده
Herein, the incorporation of TiO 2 nanoparticles (NPs), SiO NPs, and their nanocomposite (STNC) to enhance optoelectronic properties hybrid poly[9,9′‐di‐ n ‐octylfluorenyl‐2,7‐diyl] (F8), poly[2‐methoxy‐5(2‐ethylhexyl)‐1,4‐phenylenevinylene)] (MEH‐PPV), poly[2‐methoxy‐5‐(3,7‐dimethyl‐octyloxy)‐1,4‐phenylenevinylene]‐end capped with dimethylphenyl (MDMO–PPV–DMP) are revealed. The tune donor (F8) conjugated length can be detected from red shift in absorption spectra when NPs added, as well an increase emission intensity donor. addition acceptors (MEH–PPV or MDMO–PPV–DMP) results a new peak at 510 nm, which increases STNC incorporated into ternary hybrid. F8 is anticipated reduce energy bandgap improve transfer both acceptors. Moreover, Förster resonance (FRET) improved hybrid, evidenced by enhanced acceptors, increased broadness photoluminescence excitation spectra, shifting blue color toward white region. STNC‐based organic light‐emitting diode shows superior current turn‐on voltage compared other devices, likely due its FRET.

Influence of Molecular Conformations and Microstructure on the Optoelectronic Properties of Conjugated Polymers
It is increasingly obvious that the molecular conformations and the long-range arrangement that conjugated polymers can adopt under various experimental conditions in bulk, solutions or thin films, significantly impact their resulting optoelectronic properties. As a consequence, the functionalities and efficiencies of resulting organic devices, such as field-effect transistors, light-emitting d...
