ChemInform Abstract: Preparation of Red Dyes Derived from Diketo‐pyrrolo‐pyrrole Based Pigment and Their Properties for LCD Color Filters.

Abstract

Red DPP pigments (I) are prepared as an alternative to increase the contrast ratio and brightness which are crucial requirements in LCD color filter sector. UV-vis spectral properties and PPP-MO calculations are discussed; thermal stability and solubility in THF and NMP are studied as well. -(CHOI, S.-H.; KIL, G.-H.; KIM, N.-R.; YOON, C.; KIM, J.-P.; CHOI*, J.-H.; Bull.
