Electrical and optical properties of poly(2-dodecanoylsulfanyl- p-phenylenevnylene) and its application in electroluminescent devices

摘要

We describe the optical and electrical characterization of a poly(p-phenylenevinylene) derivative: poly(2-dodecanoylsulfanyl-p-phenylenevinylene) (12COS-PPV). The electrical characterization was carried out on devices with the FTOPEDOT:PSS12COS-PPV/A1 structure. Positive charge carrier mobility μ_(h) of ～1.0 × 10~(-6) cm~2 V~(-1) s~(-1) and barrier height φ of ～0.1 eV for positive charge carrier injection at the PEDOT:PSS/ 12COS-PPV interface were obtained using a thermionic injection model. FTOPEDOT:PSS12COS-PPV/Ca devices exhibited green-yellow electroluminescence with maximum emission at λ = 540 ran.
