- Synthesis, electrochemical, and spectroscopic properties of soluble perylene monoimide diesters
-
Perylene derivatives are an important class of n-type semiconductors. With the exceptions of bay-substituted and N-swallow-tail alkyl/tert-butyl substituted derivatives, most perylene diimides are insoluble. The recently reported perylene tetraesters are highly soluble, but are less electron-deficient. In this paper, a series of perylene monoimide diesters have been synthesized, which have good solubility and acceptable electron-accepting property due to the introducing of imide and ester groups in one perylene molecule. Their electrochemical properties and structural ordering were examined by cyclovoltammetry and X-ray diffraction technique, respectively. Their absorption and emission spectra are reported and discussed.

- A "green" route to perylene dyes: Direct coupling reactions of 1,8-naphthalimide and related compounds under mild conditions using a "new" base complex reagent, t-BuOK/DBN
-
The direct coupling reactions of 1,8-naphthalimide compounds efficiently occurred at 130 or 170 °C without the intervention of the leuco form dyes in the presence of base complex reagent, t-BuOK/1,5-diazabicyclo[4.3.0]non-5-ene (DBN), to give the corresponding perylene dyes in good yields with >95% purities. A possible mechanistic speculation for these oxidative coupling reactions is briefly discussed.

- Photoconductivity studies of perylene tetracarbonyl-diimides
-
Photoconductivity of a series of perylene tetracarboxyl-diimides has been studied by delayed-collection-field and electric field induced fluorescence quenching techniques.It has been shown that these materials exhibit both extrinsic (impurity controlled) and intrinsic carrier generation originating from the first excited singlet state.Perylene tetracarboxyl-diimides are photoactive in the visible spectral range and their carrier generation efficiencies compare well with generation efficiencies in the best known organic photoconductors.This makes them suitable for xerographic application using visible light.

- Process for the preparation of pigments of the perylene-3,4,9,10-tetracarboxylic acid diimide series, and their use
-
Very pure, transparent pigments of high color strength, of the formula STR1 in which R is hydrogen or alkyl having 1 to 4 C atoms, X is chlorine and/or bromine and n is a number from 0 to 4 are obtained by converting the corresponding crude pigment to the sulfate, isolating the sulfate, liberating the pure product from the sulfate by hydrolysis, separating off the pure product and dry milling the anhydrous material, with or without additives and with or without subsequent solvent finishing. These pigments are suitable for coloring paints and plastic compositions, especially for pigmenting metallic paints.
