✦ Synopsis

Triarylmethane dye ethynylogues I Trifluoromethyl group I Triphenylmethane dyes I ' Photostability I Absorption spectra Triarylmethane dye ethynylogues 7 ' -11' containing trifluoromethyl group(s) are synthesized in moderate to good yields by treating 1,1,3-triaryl-2-propyn-l-ols, prepared from diary1 ketones and lithium arylacetylides bearing trifluoromethyl group(s), with perchloric acid. The first absorption bands of a series of triarylmethane dye ethynylogues containing trifluoromethyl group(s) l l ' are observed around 700 nm. The photostability of the triarylmethane dyes is also examined.
