Molecular Formula: C21H16N2
Lophine (2,4,5-triphenyl-1H-imidazole) exhibits lemon yellow chemiluminescence in solution and is one of the few long-lasting chemiluminescent molecules.Chemiluminescence (sometimes "chemoluminescence") is the emission of light (luminescence) with limited emission of heat as the result of a chemical reaction.(wikipedia)
It forms dimers that have piezochromic and photochromic properties. It has been proposed as an analytical reagent for trace metal ion detection.
Lophine’s chemiluminescence was discovered by B. Radziszewski in 1877.
