Electronic Structure of the cis and trans Isomers of Benzimidazo Perylene Derivatives and their Use as Black Pigments
Abstract:Peryleneimide compounds are industrially important pigments in paint industries as well as in electronics areas. We have focused on the title compound (BIP) as a potential substitute for carbon black used widely as the black pigment. For this reason, electronic characterization of the cis and trans form of BIP has been carried out on the basis of the crystal structure and intermolecular interactions. The black color is characterized by two absorption bands in the visible region in both isomers: the former, shorterwavelength band is due to individual molecules and the latter, longer-wavelength band appears as a result of excitonic interactions between transition dipoles. The stack molecule-pairs, among others, play the determinant role in the appearance of the longer-wavelength band to cover the whole visible region together with the molecular band.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
