A series of perylene tetracarboxylic bisimides, substituted at the N‐position with methoxyphenyl groups, have been synthesized together with model compounds and their photophysical properties have been investigated by means of steady‐state and time‐resolved spectroscopic techniques. The luminescence properties of the examined compounds vary remarkably with the substitution pattern, with emission quantum
