High-performance black color paste and preparation method thereof

The invention relates to the technical field of black pigments, in particular to a high-performance black color paste and a preparation method thereof. The preparation process does not need to be subjected to grinding treatment, can be highly dispersed in the low-melting-point amphiphilic solid, can effectively improve the workability and repeatability, and reduces the chromatic aberration 10% - 1000%. The preparation method disclosed by the invention causes the components to react and discolor in the kneading machine, finally obtains the black color paste, and is simple in preparation step, easy and convenient to operate, easy to prepare and good in application prospect.

Green synthesis of polycyclic benzimidazole derivatives and organic semiconductors

Polycyclic benzimidazole derivatives, an important class of compounds in organic electronics and photovoltaics, were prepared using a solvent-free "green" process based on heating carboxylic acid anhydrides and arylene diamines in the presence of zinc acetate in the solid state. Products were isolated and purified directly by train sublimation of the crude reaction mixtures. The reaction conditions were optimized using various carboxylic acid anhydrides. Optical and electrochemical properties of these materials are also described.

BLACK PERYLENE PIGMENTS

Disclosed are black perylene pigments containing one of the isomers of formula (Ia) or (Ib), wherein the variables have the following meaning: R1, R2 independently represent phenylene, naphthylene, or pyridylene, each of which can be monosubstituted or polysubstituted by C1-C12 alkyl, C1-C6 alkoxy, hydroxy, nitro, and/or halogen; X represents halogen; n represents 0 to 4. The inventive black perylene pigments alternatively contain a mixture of both isomers and are provided with a black number ≥ 210 in an alkyd/melamine baking enamel.
