Triphenylmethanes

Part of speech: noun

Definitions

1. Organic compounds built around a central carbon atom bonded to three phenyl rings, many of which serve as intensely colored dyes
2. Chemical substances whose core structure is a methane carbon carrying three benzene rings, often used as vivid synthetic colorants
3. A family of aromatic hydrocarbon derivatives featuring three phenyl groups attached to one carbon, forming the basis of many bright dyes

Etymology: "Triphenylmethanes" is simply the plural of "triphenylmethane", a chemical compound whose name is built from two systematic parts. "Methane" is the simplest hydrocarbon, a molecule with one carbon atom bonded to four hydrogens, and the chemical naming system takes that carbon as the backbone. "Triphenyl" means three "phenyl" groups attached to it. "Phenyl" is the name for a ring of six carbon atoms, the same ring found in benzene, with one hydrogen removed so that it can bond to something else. Put together, the name describes the structure directly: a central carbon atom carrying three phenyl rings and one remaining hydrogen. Chemists use the plural form when referring to the whole family of compounds built on this same skeleton, with different groups substituted onto the rings.
