9-anthryl
|9-an-thryl|
/ˌnaɪnˈænθrɪl/
anthracene 9-position substituent/radical
Etymology
'9-anthryl' is formed from 'anthryl' (the substituent name) combined with the locant '9-'; 'anthryl' in turn derives from 'anthracene', which comes from Greek 'ánthrax' via Medieval Latin/Modern French, where 'ánthrax' originally meant 'coal'.
'anthryl' developed as a substituent name from the parent hydrocarbon 'anthracene' (named in the 19th century), and adding the locant produced terms like '9-anthryl' to specify substitution at the 9-position of anthracene.
Initially associated with the parent hydrocarbon 'anthracene' (a coal-tar derived aromatic hydrocarbon); over time specialized substituent/radical names like 'anthryl' and locanted forms such as '9-anthryl' came to denote specific bonded fragments or radicals used in organic chemistry.
Meanings by Part of Speech

a radical or substituent group derived from anthracene by removal of a hydrogen atom at the 9-position (formula C14H9 when radical). Used to denote a 9-substituted anthracene fragment attached to another atom or group.
The 9-anthryl substituent was introduced to study how a bulky aromatic group affects the molecule's electronic properties.
