Soluble Perylene Fluorescent Dyes with High Photostability

Rademacher, Andreas,Maerkle, Suse,Langhals, Heinz

, p. 2927 - 2934 (2007/10/02)

The preparation of several 3,4,9,10-perylenebis(dicarboximides) 1 is described and their photostability quantitatively determined and discussed.It is shown, that substitution of the insoluble perylene dye pigments with tert-butyl groups causes solubility in organic solvents leading to high quantum yields of these dyes.
