Abstract Triarylmethane dye ethynylogues 7 ′– 11 ′ containing trifluoromethyl group(s) are synthesized in moderate to good yields by treating 1,1,3‐triaryl‐2‐propyn‐1‐ols, prepared from diaryl 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) 11 ′ are observed around 700 nm. The photostability of the triarylmethane dyes is also examined.
