Photogeneration of charges carriers and their transport properties in poly[bis(p-n-butylphenyl)silane]

Article Abstract:

The photocarrier generation mechanism and mobility in poly[bis(p-n-butylphenyl)silane] (PBPS) thin films doped with a variety of electron acceptors are studied by time-resolving microwave conductivity (TRMC) measurements. It was found that fullerence is a suitable electron acceptor for PBPS as it provides the highest product of photocarrier generation yield and the result shows that the high charge carrier mobility of PBPS polymer makes it a potential material for use in optoelectronic devices.

Electronic structure and optical properties of charged oligofluorenes studied by VIS/NIR spectroscopy and time-dependent density functional theory

Article Abstract:

The electronic structure and optical properties of charged oligofluorenes are studied experimentally and theoretically. The optical absorption spectra of charged oligofluorenes are dependent on the angle between neighboring units.
