Research on perinone compounds

Perinone—New Life of an Old Molecule

“…Another way to increase the solubility of perinone derivatives was to use aromatic diamines or tetraamines substituted with long or branched alkyl chains. Li et al [56] applied 2,3,6,7-tetraamino-9,9-bis(2-ethyl-hexyl)fluoren (31) in condensation reaction with 12 for synthesis of symmetrical bisperinone derivatives (32), as shown in Figure 12. The color of all stereoisomers 30 and 30a is the same with the maximum absorption peak located around 484 nm and luminescence peak at 616 nm.…”

“…Modification of perylene pigments (Scheme 1) offers a relatively simple way to synthesize compounds with absorbance covering the whole range of the visible spectrum. Perinone is a molecule obtained in the laboratory of Hoechst in Frankfurt-on-the Main, Germany, over ninety-five years ago, [25][26][27][28] and it was used as a pigment in the dye industry [29][30][31]. Studies summarizing these applications have been published systematically over the past 30 years [23,[32][33][34].…”
