Facile synthetic approach to novel core-extended perylene carboximide dyes.
The straightforward synthesis of two new classes of core-extended perylene chromophores, dibenzocoronene tetracarboxdiimide and indenoperylene dicarboxmonoimide, proves that directional enlargement of the aromatic pi-system leads to tailored bathochromic and hypsochromic shifts.
