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

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 FTO\PEDOT:PSS\12COS-PPV/Al structure. Positive charge carrier mobilit...

Description
Summary:	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 FTO\PEDOT:PSS\12COS-PPV/Al 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. FTO\PEDOT:PSS\12COS-PPV/Ca devices exhibited green-yellow electroluminescence with maximum emission at λ = 540 nm.
