“…Composite systems based on polymers that are embedded in mesoporous materials with nanoscale pores are the new class of structures, which allow the investigation of and the control over polymer properties in the transition from films to nanostructures. These studies also encourage the use of ultrathin polysilane films as transport layers in electroluminescent devices [12] or as active electroluminescent materials in the UV region, sensors, and photoresistors [13][14][15]. The interaction of polymers with pore surfaces and the intermolecular interactions between polymer chains significantly influence the optical properties of composite films.…”

Optimal technological conditions for the fabrication of nanocomposite films based on the poly(di-n-hexylsilane) (PDHS) incorporated into a TiO2 nanoporous film have been developed, and such composites are fabricated. Their optical spectra have been investigated in a wide temperature range (15–330) K. It is shown that the distinctive feature of nanocomposite films is related to the predominant fluorescence band of aggregates with respect to the fluorescence bands corresponding to the gauche- and trans-conformations of polymer chains and to the observation of the intense fluorescence band of aggregates even at room temperature.

“…Polarizabilities. The CPHF/6-31+G(d) static first hyperpolarizabilities of PMS ( = 2, 4, 6,8,10,12,14), as calculated for different chain lengths, are given in Table 6. From this table it can be seen that (i) component, which represents for the value in the longitudinal direction of the Si-Si skeleton, makes the dominant contribution to 0 and increases much faster than the others; (ii) 0 , 0 , and 0 increase as the chain length elongated; however, the amount of increase for each component is discriminating.…”

“…In recent years, polysilanes have attracted increasingly extensive attention due to their unique physical and chemical properties resulting from -electrons delocalized along the silicon backbone. In this regard, they have resulted in a variety of technological applications, such as conductor and semiconductor [1], photoconductive materials [2], organic multilayer, light emitting diodes (LEDs) [3], high-density optical data storage materials [4], electro luminescence (EL) devices [5,6], and nonlinear optical (NLO) materials [7,8].…”

The static linear and nonlinear optical properties of the -conjugated polymer -t-Bu--CN-poly(methylphenyl)silane (PMS) are studied at the Coupled-Perturbed Hartree-Fock (CPHF) level with 6-31+G(d) basis set. The calculated results reveal that the static first hyperpolarizabilities of this system increase with the main chain length and have a good agreement with experiments. The (hyper)polarizabilities per unit cell have been extrapolated to infinite chain limit and a comparison is made to those of polysilane and polyacetylene (PA). Besides, other structural properties depending on the -conjugated Si-Si skeleton length are investigated as well. Electron correlation effect is estimated and it turns out that the MP2 static first hyperpolarizability is about 1.5 ∼ 2.0 times larger than the corresponding CPHF value for the polymer with ≤ 6.

The discovery of a remarkable class of plastics that can conduct electricity has opened a new era of plastics science and technology that has just been recognized by the award of the 2000 Nobel prize for chemistry. They can be used to make a wide range of electronic devices such as transistors, light‐emitting diodes, solar cells and even lasers, through much simpler manufacture than conventional inorganic materials, increasing flexibility, reducing cost, and opening up new markets. Polysilanes are subject of an intensive research work aiming to various optoelectronic applications. Through this work the chemical structure of polydiphenylsilane was modified to obtain both solubility in common solvents and to induce new properties by attaching of various organic segments.
