Core-Extended Perylene Tetracarboxdiimides: The Homologous Series of Coronene Tetracarboxdiimides

Abstract

Two novel coronenediimide (CDI) derivatives, CDI 2 and dinaphtho-CDI 4, were synthesized via straightforward synthetic routes completing the homologous series of coronene tetracarboxdiimides, which show remarkable optical properties with absorption wavelengths ranging from 380 to 600 nm, high absorption coefficients, and high fluorescence quantum yields.
