Synthesis, photophysical properties, and nanocrystal formation of a new class of tetra-n-substituted perylenes

A new class of perylene-derived dyes, tetra (carboxamido) perylenes, has been obtained by a generally applicable synthetic method. Derivative A is shown to form nanocrystalline aggregates in DMSO which display significantly modified photophysical behavior with respect to the monomer and were studied by using atomic force microscopy techniques.
