Synthesis of maleimidotriethoxy silane-series compounds, and preparation method of self-assembled film

Abstract

Among various factors influencing performances of organic electronic components, interfacial property is the most important one influencing the performance of the whole component. In the invention, a series of maleimidotriethoxy silane-series compounds are synthesized, wherein a monomolecular film layer is formed on a surface of an oxide substrate through a self-assembling method, thereby modifying the substrate. Dicyclopentadiene platinum chloride is employed as a catalyst to perform hydrosilylation. Nuclear magnetism is carried out for representation. A test result proves that the catalyst allows catalytic addition to a compound having an amino group to be carried out high-efficiently, and furthermore, silicone on a silanoethoxyl group is connected to a position of a terminal group of a double bond before addition. A self-assembling method is utilized to form the monomolecular film layer on the surface of the oxide substrate. A Young contact angle instrument and XPS is employed for representation, which proves that a flat monomolecular film layer is formed on the surface of the oxide substrate.

Description

technical field [0001] The invention uses a series of triethoxysilane compounds to form a monomolecular film on the surface of an oxide substrate by self-assembly, thereby realizing the modification of the substrate. Background technique [0002] Among the many factors affecting the performance of organic electronic devices, the interface properties have a crucial impact on the performance of the entire device. Because the interface properties affect the growth of organic materials, resulting in changes in the microstructure of thin films, and ultimately affect the performance of organic electronic devices, so the modification of substrates with organic film materials has become an important means to improve interface properties. The organic material commonly used to modify oxide substrates is alkylsilane RSi(OEt) 3 , modified substrates have been widely used in the field of devices (N. Herzer, S. Hoeppener, U.S. Schubert, Chem. Commun. 2010, 46, 5634-5652.). One advantage...
