Radiative recombination and vibronic relaxation in σ-delocalized silicon-backbone-network polymers: Energy thermalization in poly(n-hexylsilyne)

Autor: T. W. Weidman, William L. Wilson

Publikováno v: Physical Review B. 48:2169-2174

The nature of ultrafast energy dissipation in poly(n-hexylsilyne), a prototypical σ-delocalized alkylsilicon-network polymer is reported. This disordered, silicon-backbone material exhibits strong near-UV to visible band-edge absorption and a high q

Excited-state dynamics of one- and two-dimensional .sigma.-conjugated silicon frame polymers: dramatic effects of branching in a series of hexylsilyne-branched poly(hexylmethylsilylene) copolymers

Autor: William L. Wilson, T. W. Weidman

Publikováno v: The Journal of Physical Chemistry. 95:4568-4572

Time-resolved single photon counting techniques were used to compare and contrast the luminescence behavior of linear poly(hexylmethylsilylene), poly(hexylsilyne), and three copolymers incorporating nominally 1%, 5%, and 25% hexylsilyne branch points

Photophysical Dynamics of the [sgrave]-Delocalized Network Alkylpolysilynes: (R-Si)n

Autor: William L. Wilson, T. W. Weidman

Publikováno v: Molecular Crystals and Liquid Crystals. 194:85-91

We review the first transient photophysical data on the “ polysilynes ”, a new class of extensively crosslinked silicon skeletal polymeric materials. Using steady-state and picosecond spectroscopic...

Propagation loss of index imaged poly(cyclohexylsilyne) thin film optical waveguides

Autor: L. A. Hornak, T. W. Weidman

Publikováno v: Applied Physics Letters. 62:913-915

The propagation loss of optical waveguides index imaged in a 0.5 μm poly(cyclohexylsilyne) (PCHS) film through photo‐oxidative cross linking with ultraviolet exposure at 310 nm is measured and compared to an experimental estimate of PCHS bulk prop
