Highly efficient red-electrophosphorescent devices based on polyfluorene copolymers containing charge-transporting pendent units

Article Abstract:

The photoluminescence (PL) and electroluminescence (EL) behavior of blends comprising two efficient red phosphors doped into the blue-emitting polyfluorene derivatives PF-TPA-OXD and PF-OXD are examined. The host-polymers, which contain both hole-transporting and electron-transporting or only electron transporting side chains, are capable of facilitating charge injection and transport.

Charge transport at metal-molecule interfaces: A spectroscopic view

Article Abstract:

The way an electron crosses a metal molecule has been a question long-standing in many disciplines. The recent surge of interest in molecule-based conventional electronic devices, such as organic light-emitting diodes, the metal-molecule interface determines the charge-injection efficiency.

Kinetics of catalytic isomerization of quadricyclane to norbornadiene using near infrared absorption spectroscopy: Conversion rate and diffusion motion in heterogeneous reaction

Article Abstract:

The conversion of quadricyclane to norbornadiene catalyzed by anhrdrous CuSO4 and SnCl2 in chloroform has been investigated with the use Fourier transform new-infrared (NIR) absorption and the aid of a kinetic model.
