Abstract

Abstract A series of highly soluble and fluorescent core-twisted perylene bisimide dyes (PBIs) 3 a–f with different substituents at the bay area (1, 6, 7, 12 positions of the perylene core) were synthesized and fully characterized by 1 H NMR, UV/Vis spectroscopy, MS spectrometry, and elemental analysis. The π–π aggregation properties of these new functional dyes were investigated in detail both in solution and in condensed phase by UV ...
