摘要：

Quaterrylenetetracarboxylic bisimides are prepared from perylene-3,4:9,10-tetracarboxylic bisanhydride via perylene-3,4-dicarboxylic imides which are dimerized in molten alkali. The unsubstituted bisimide is an insoluble black pigment. N-substitution with the solubility-increasing 1-hexylheptyl group gives a soluble dye with a remarkably strong fluorescence in the NIR region (816 nm).
