PERYLENE-3,4,9,10-TETRACARBOXYLIC-ACID DIIMIDES AND THEIR USE |
摘要 |
A process for concentrating light by means of fluorescent compounds of the formula <IMAGE> (I) where the R1's independently of one another are ortho-substituted aromatic or heterocyclic radicals which do not contain groups which confer solubility in water, and novel perylene-3,4,9,10-tetracarboxylic acid diimides of the formula I, where R1 is <IMAGE> A1 and A2 being hydrogen, or one of A1 or A2 being isopropyl and the other being hydrogen. The compounds I are very lightfast and convert incident light into fluorescent light with high efficiency. |
