Oligopeptides are short-chain peptides formed by a small number of amino acid residues linked through peptide bonds. According to biochemical nomenclature materials from the International Union of Pure and Applied Chemistry (IUPAC), peptides containing fewer than approximately 10–20 amino acid ...
IUPAC defines fluorescence as: a process in which an excited molecule spontaneously emits radiation while preserving the spin multiplicity (simplified: absorb light → emit light shortly after).
A broader umbrella term is photostabilizers / light stabilizers. In polymer terminology, IUPAC defines a light stabilizer as an additive incorporated into a material to protect polymers from photodegradation. In industrial contexts, systems aimed at mitigating UV-driven aging are often ...
