A novel synthetic strategy to develop second‐order nonlinear optical polysilanes for potential photorefractive effects

Synthesis and nonlinear optical properties of polyphosphazenes with binaphtholyl and indole side groups

“…Generally, the d 33 value of the same NLO polymer can be different when measured by different methods or different testing systems. Compared with the values of other polymers containing similar azo chromophores tested by the same equipment, the d 33 values of P2 and P3 are relatively high 28–33. They should be due to the high β value of indole azo chromophores10 and the presence of some spacer between the chromophore side chains and the backbone.…”

A facile method to prepare a polyethylene glycol modified polysilane as a waterborne photoinitiator

“…Similar as literature procedure [43], to a sodium metal dispersion (4.6 g, 0.2 mol) in 50 mL of dry toluene was added dropwise a solution of methylpenyldichlorosilane (19.1 g, 0.1 mol) in 20 mL of dry toluene at a rate sufficient to maintain vigorous reflux. After that, the mixture was heated at reflux for an additional 6 h and then cooled to room temperature.…”

“…Polysilane 4 was prepared by a traditional Wurtz condensation by methylphenyldichlorosilane and sodium in toluene [43]. In order to introduce hydrophilic component into the polymer chain, polyethyleneglycol (with an average molecular weight as high as 550) was chosen to prepare the acrylate functionalized polyethyleneglycol 5, which was then photopolymerized with polysilane 4.…”

Theoretical Study on the Static (Hyper)Polarizabilities of α-t-Bu-ω-CN-Poly(methylphenyl)silane

“…Shi et al [10] have synthesized poly(methylphenyl)silane (PMPS) and measured its third-order nonlinear optical susceptibility (3) of 5.8 ×10 −12 esu by third harmonic generation (THG) with a pulse laser width at 1064 nm for thin films. Then, Tang and coworkers [11] have explored a novel strategy to develop polysilanes functionalized with a high density of nonlinear optical chromophores and the poled film reveals a resonant 2 Advances in Physical Chemistry susceptibility of PMPS derivatives be? There is little scientific attention from the theoretical point of view.…”
