[0307] (Preparation of composition for organic semiconductor alignment)

[0308] The composition for aligning organic semiconductors of the present invention, as described above, contains a photo-alignment polyorganosiloxane compound as an essential component, and may contain other optional components as needed. It is preferable to dissolve each component in an organic solvent and prepare a solution. combination. In addition, the photo-alignment polyorganosiloxane compound and other components (for example, at least one polymer selected from the group consisting of polyamic acid and polyimide and other polyorganosiloxane etc.) In any state of the organic semiconductor alignment composition and the organic semiconductor alignment film, a part may be connected to each other.

[0309] As the organic solvent that can be used to prepare the composition for organic semiconductor alignment of the present invention, a solvent that dissolves the photo-alignment polyorganosiloxane comp...

Synthetic example 1

[0358] In a reaction vessel with a stirrer, a thermometer, a dropping funnel and a reflux condenser, add 100.0 g of 2-(3,4-epoxycyclohexyl) ethyltrimethoxysilane (ECETS), 500 g of methyl iso Butyl ketone and 10.0 g of triethylamine were mixed at room temperature.

[0359]Next, after adding 100 g of deionized water dropwise over 30 minutes from the dropping funnel, it was reacted at 80° C. for 6 hours while mixing under reflux. After the reaction, the organic layer was taken out, washed with 0.2 mass % ammonium nitrate aqueous solution until the washed water was neutral, and the solvent and water were distilled off under reduced pressure to obtain polyorganosiloxane with epoxy groups, which was viscous transparent liquid.

[0360] The polyorganosiloxane with epoxy group is carried out 1 In H-NMR analysis, a peak due to the epoxy group of theoretical intensity was obtained around chemical shift (δ) = 3.2 ppm, and it was confirmed that no side reaction occurred in the epoxy gro...

[0362] Polyorganosiloxanes having epoxy groups were obtained as viscous transparent liquids in the same manner as in Synthesis Example 1, except that the raw materials added were as shown in Table 1. Table 1 shows the Mw and epoxy equivalent of the obtained epoxy group-containing polyorganosiloxane.

Description

technical field [0001] The present invention relates to an organic semiconductor alignment composition suitable as a composition for forming an organic semiconductor alignment film, an organic semiconductor alignment film formed from the composition, an organic semiconductor element having the organic semiconductor alignment film, and a method for producing the same. Background technique [0002] In recent years, liquid crystal display elements are suitable for use in a wide range of applications ranging from small liquid crystal display devices such as mobile phones to large-screen liquid crystal display devices such as liquid crystal televisions due to their advantages of low power consumption and ease of miniaturization and flat panelization. In such a liquid crystal display element, an image can be displayed by switching the liquid crystal allocated to each dot on and off, and a thin film transistor (TFT) is used for switching the liquid crystal on and off. [0003] As s...
