Problems solved by technology

However, the method of said document requires a complex two-step reaction, moreover, only two reactive substituents can be introduced into one polysilane molecule at most
Therefore, molecular design (such as high-density introduction of active substituents or large changes in solubility in solvents) is limited

Embodiment 1

[0167](Example 1) Add 25g of magnesium particles (particle size: 20-1000m) and 20g of lithium chloride catalyst to a round bottom flask (internal volume: 1000ml) with a three-way cock, heat at 50°C and 1mmHg (=133Pa) under low pressure The contents of the reaction vessel (flask) were dried. Then, dry argon gas was introduced into the reaction vessel, 500 ml of tetrahydrofuran (THF) pre-dried using sodium-benzophenoneketyl was added thereto, and the mixture was stirred at 25° C. for about 60 minutes. 63.5 g (0.3 mol) of phenyltrichlorosilane purified by distillation and 34.5 g (0.3 mol) of methyldichlorosilane purified by distillation were added to the reaction mixture by syringe, and the resulting mixture was stirred at 25° C. for about 24 hours. After the reaction was completed, 1000 ml of 1N (=1 mol / L) hydrochloric acid was added to the reaction mixture, and the reaction mixture was extracted with 500 ml of toluene. Utilize 200ml aliquots of pure water to wash the toluene l...

Embodiment 2

[0169] (Example 2) 11.2 g of a copolysilane having a carboxyl group (yield: 100%) was obtained in a similar manner to Example 1 except that 5.0 g of ethyl acrylate in Example 1 was replaced with 3.7 g (50 mmol) of acrylic acid.

Embodiment 3

[0170] (Example 3) 11.2 g of a copolysilane having a carboxyl group (yield: 100%) was obtained in a similar manner to Example 2, except that 0.41 g of AIBN in Example 2 was replaced by 0.061 g of dibenzoyl peroxide.

Abstract

Disclosed is a polysilane having excellent functionality (such as solvent solubility and reactivity), which is obtained by introducing a structural unit represented by the formula (1) below into a polysilane through a reaction with a dihalosilane having an Si-H bond and then adding a hydrosilylatable compound (such as a compound having a carbon-carbon unsaturated bond) to the Si-H bond. (1) (In the formula, R<1> represents a hydrogen atom, an organic group or a silyl group, and n represents an integer not less than 1.)

Description

technical field [0001] The present invention relates to functional polysilanes having imparted excellent functions such as solubility and reactivity in solvents, methods for preparing said polysilanes, and polysilanes comprising said polysilanes. Silane resin composition. Background technique [0002] Polysilane is a polymer compound with a main chain of silicon-silicon bonds, and it also has various physical properties (such as heat resistance, high refractive index, photoreactivity, hole transport, luminescence, etch resistance and low dielectric properties). constant) material. Because of such excellent physical properties, polysilanes are used as ceramic precursors, interlayer insulating films and optoelectronic materials (such as photoresists, photophotographic materials (such as organic photoreceptors), light-transmitting materials (such as light guides), optical recording materials, etc. Materials (such as optical memory and electroluminescent devices) have attracte...
