Perylenecarboxylic anhydride imides were condensed with semicarbazide and thiosemicarbazide to obtain strongly red‐fluorescent triazolinone and triazolinthione derivatives, respectively, suitable for nucleophilic labelling. A Schönberg reaction of the latter with diazoalkanes allowed the synthesis of spirothiiranes.
