Notizen:
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.
