Lophine is the organic compound with the formula (C6H5C)2N2HCC6H5. It is a derivative of imidazole wherein all three carbon atoms have phenyl groups as substituents. A white solid, this compound gave the first example of chemiluminescence when its basic solutions were exposed to air.[1] Its chemiluminescence continues to attract attention.[2]
Lophine is prepared by condensation of benzaldehyde, benzil, and ammonia.[3]
