Diketopyrrolopyrroles are typical hydrogen-bonded pigments of red color based on the skeleton of 1,4-diketo-3,6-diphenylpyrrolo[3,4-c]pyrrole (DPP). Our previous investigation revealed that the 1:1 mixed crystal (MX-DPP) composed of DPP and its (t-butylphenyl) derivative (BTB-DPP) gives practically the same electronic spectra as well as X-ray diffraction diagram as those of the hybrid compound of DPP and BTB-DPP (MTB-DPP). In order to elucidate the present coincidence, electronic structure has been investigated on single crystals of MX-DPP and MTB-DPP on the basis of the structure analysis. The space groups of both crystals are found to be the same (P-1) and the crystallographic parameters are quite similar. In both MX-DPP and MTB-DPP, the same molecular environment (in other words, the “local similarity”) is achieved throughout the crystal. Furthermore, the polarized reflection spectra measured on single crystals also gave approximately the same results. These experimental facts led us to conclude that the “local similarity” plays the key role in the determination of the crystal and electronic structures in MX-DPP and MTB-DPP.

  • For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
