Usage

Uses

Pigment red 149 (CAS# 4948-15-6) is a perylenediimide dye, and has been proposed for use as cost-efficient cathodes for lithium ion batteries. Pigment red 149 has also been implemented as a doping agent for poly(styrene-co-maleimide) nanoparticles for use as bioprobes for biotinylated antibodies.

A perylene pigment preparation method

The present invention provides a perylene pigment preparation method, is to adopt the N - substituted - 1, 8 - naphthalene imide as the starting material, in order to N - methyl imidazole with DBU or DBN N - methyl imidazole with the mixed solvent as reaction medium, sodium alcoholate or polysiloxane as catalyst, through 130 - 170 °C reaction 3 - 10 hours, after the reaction, the reaction system cooling, concentrated under reduced pressure, recycling the reaction solvent, collects the product make the perylene pigment. Preparation of perylene pigment coloring high, bright color, good dispersibility, and this process is simple, time consuming and short, the reaction temperature is low, to reduce the use of strong alkali and concentrated sulfuric acid, the production cost is reduced, the reduction of the waste water and the solid waste discharge.

Soluble Perylene Fluorescent Dyes with High Photostability

The preparation of several 3,4,9,10-perylenebis(dicarboximides) 1 is described and their photostability quantitatively determined and discussed.It is shown, that substitution of the insoluble perylene dye pigments with tert-butyl groups causes solubility in organic solvents leading to high quantum yields of these dyes.
