Problems solved by technology

However, diimine-based compounds that use halide ions as anions are difficult to apply to projects that use them as near-infrared absorbing materials due to solubility problems.
Due to the high solubility of organic carbonate ions in water, it is practically difficult to apply, which makes it difficult to control the yield in the production process based on diimine compounds, and causes problems in the weather resistance of products
However, anion materials widely used recently, such as fluoroantimoni (fluoroantimoni) acid ions, can be used as near-infrared absorbing materials due to their suitable properties, but they are not suitable for use in places closely related to human living environments, such as houses and cars, because Fluorine atoms are present in the material, toxic substances such as hydrofluoric acid may be released, and the durability of products such as films is also reduced due to hydrofluoric acid

Embodiment 1

[0028] Example 1: Preparation of diimine-based compound (N, N, N', N'-tetrakis(p-diisobutylaminobenzene) p-phenylenedimine (N, N, N', N'-tetrakis( p-diisobutylaminophenyl)-p-phenylene diimmonium)

[0029] 12g N,N,N',N'-tetrakis(4-aminophenyl)-1,4-p-phenylenediamine (N,N,N',N'-tetrakis(4-aminophenyl)-1,4- Phenylenediamine), 40g isobutylbromide and 18g sodium bicarbonate were added to a three-necked flask with a reflux device, and then 30g N-methylpyrrolidone (N-methylpyrrolidone) was added, and the mixture was stirred and reacted at 80°C for 9 hours . After the reaction was completed, 300 g of dichloromethane and 1 L of water were added to the flask, followed by stirring for 30 minutes. After stirring, distill the separated dichloromethane layer with a vacuum distiller to obtain 30 g of N,N,N',N'-tetrakis(p-diisobutylaminobenzene)-p-phenylenediamine (primary reactant).

Description

technical field [0001] The present invention relates to a diimine-based compound and a near-infrared absorption filter using the same, and more particularly to a novel diimine-based compound which has low light absorption in the visible region but has a low light absorption in the near-infrared The light absorption efficiency of the area is very high, and it has superior durability and weather resistance, and it also involves a near-infrared absorption filter using the compound. Background technique [0002] Since energy usage has reached its limit, all industrial fields are actively developing and applying energy-saving materials. Generally, a near-infrared ray absorbing material (pigment) is used to prevent electronic equipment from malfunctioning by blocking near-infrared rays generated by the electronic equipment. But when a film containing the material is applied to windows, it absorbs some of the sunlight, reducing heat exchange between the interior and exterior, prev...
