蛍光性ジケトピロロピロール類似体
Document Type and Number:
Japanese Patent JP2004537638
Kind Code:
A
Abstract:
The present invention relates to fluorescent diketopyrrolopyrrole analogues of the general formula (I), wherein A1 and A2 are C1-C18alkyl, C2-C18alkenyl, C2-C18alkynyl, C5-C8cycloalkyl, C5-C8cycloalkenyl, aryl or heteroaryl, A3 and A4 are independently of each other C1-C18alkyl, Ar3, -CR30R31-(CH2)m-Ar3, or Y-R32, wherein R30 and R31 independently of each other stand for hydrogen or C1-C4alkyl, or phenyl which can be substituted up to three times with C1-C3alkyl, Ar3 stands for aryl, in particular phenyl or 1- or 2-naphthyl, C5-C8cycloalkyl, in particular cyclohexyl, or heteroaryl, which can be substituted one to three times with C1-C8alkyl, C1-C8alkoxy, halogen or phenyl, which can be substituted with C1-C8alkyl or C1-C8alkoxy one to three times, and m stands for 0, 1, 2, 3 or 4, Y is C(O)- or SO2- and R32 is C1-C18alkyl, Ar3, or aralkyl and A3 can additionally be hydrogen, C1-C8alkyloxycarbonyl, such as tertbutoxycarbonyl, or aralkyloxycarbonyl, such as benzyloxycarbonyl, a process for their preparation and their use for the preparation of inks, colourants, pigmented plastics for coatings, non-impact printing material, colour filters, cosmetics, polymeric ink particles, toners, dye lasers and electroluminescent devices, or as fluorescent markers for immunoassays and fluorescent tracers for leak detection of fluids. The diketopyrrolopyrrole analogues of the general formula I show a high solid state fluorescence
