We developed a novel coupler, hydroxyperinone, 2- and/or 5-hydroxy-7H-benz[de]benzimidazo[2,1-a]isoquinoline-7-one and synthesized a bisazo pigment from the novel coupler. The OPC using this bisaszo pigments showed better characteristics in sensitivity and cyclic stability than the OPC using bisazo pigments derived from Naphthol AS. 13C NMR spectra of these bisazo pigments indicated that the dominant tautomer of the new bisazo pigment in the solid state was different from those of other bisazo pigments. The difference in tautomers reflects their characteristics. We designed and synthesized a unique highly sensitive unsymmetrical bisazo pigment having a large dipole moment in the excited state, on the basis of the photocarrier generation process model. Thermally stimulated current measurements were applied to elucidate factors for high sensitivity.

More about this publication?
  • The Journal of Imaging Science and Technology (JIST) is dedicated to the advancement of imaging science knowledge, the practical applications of such knowledge, and how imaging science relates to other fields of study. The pages of this journal are open to reports of new theoretical or experimental results, and to comprehensive reviews. Only original manuscripts that have not been previously published, nor currently submitted for publication elsewhere, should be submitted.

    IS&T's JIST-first publication option allows authors wishing to present their work at conferences, but have a journal citation for their paper, to submit a paper to JIST that follows the same rigorous peer-review vetting and publication process as traditional JIST articles, but with the benefit of a condensed time-to-publication time frame and guaranteed conference presentation slot.

    Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in perpetuity. Copyright restrictions on papers vary; see individual paper for details.
