Spin dependent recombination in conjugated polymers: An optically detected magnetic resonance study

摘要

This work describes and discusses Photoluminescence (PL), and X-band Photoluminescence Detected Magnetic Resonance (PLDMR) of poly(3-alkylthiophene) (P3AT) films and solutions, poly(para-phenylenevinylene) (PPV), poly(2,5-dihexoxyparaphenylenevinylene) (PDHOPV), poly(2,5-dioctoxyparaphenylenevinylene) (PDOOPV), blends of poly(2-methoxy,5-(2'ethylhexoxy)paraphenylenevinylene) (PMOEHOPV) with polyethylene (PE) films both unoriented and oriented, and poly(2,5-dibutoxyparaphenyleneacetylene) (PDBOPA) films. The Electroluminescence Detected Magnetic Resonance (ELDMR) and Conductivity Detected Magnetic Resonance (CDMR) narrow quenching signal in PPV is also reported and discussed.
