The object of the invention consists of D-luciferin derivatives of General Formula (I) ##STR1## wherein R.sup.1 =OH, alkoxy, alkenyloxy, amino acid, NH.sub.2 or oligopeptide and R.sup.2 =H; H.sub.2 PO.sub.3 --; HSO.sub.3 --; alkyl or alkenyl, optionally substituted by phenyl; aryl; ##STR2## with R.sup.3 =alkyl or alkenyl, optionally substituted by phenyl; mono- or disaccharide or nucleotide. An object of the invention is further the use of said luciferin derivatives for the detection of ligands in the determination of biochemical substances, in particular in enzyme immuno assays, in blot processes and in nucleic acid hybridization. These ligands are attached to an enzyme (enzyme conjugate). In the process, for example an antigen, a hapten or an antibody is conjugated with an enzyme. The enzyme conjugate is capable of releasing luciferin from the luciferin derivative. The luciferin released is reacted with luciferase. The amount of light emitted in the process is determined. From the data obtained in this manner, the quantity of the substances to be determined may be derived.
