The present invention describes a bioconjugation strategy and compounds that are useful therein in which a fluorescent signal is produced when two molecular or supramolecular entities are linked by chemoselective combination of one linker having an azido or halide substituent group with another linker having a cyano or an alkyne substituent group. A kit is also provided.

An anthrapyridone composition of the formula: is disclosed, where 'A' and 'B' are independently selected from substituted or unsubstituted cyclic ketone groups having from about 10 to about 20 ring carbon atoms; &#x201c;a&#x201d; is an integer having a value from 0-4, R-Rare monovalent substituents; with the proviso that when &#x201c;a&#x201d; is 0, Ris selected from the group consisting of a hydrogen, an alkyl group, a secondary amino group and an aminosulphonyl group; and R-Rare substituents selected form the group consisting of a hydroxyl group, an aliphatic group, an aromatic group, a heterocyclic group, a halogen atom, a cyano group, a carbonyl containing group, an amino group and a sulphonyl-containing group. The anthrapyridones are useful as thermally stable colorants for producing colored polymer resins and articles that require high temperature polymer processing conditions.
