A phosphine-gold(I)-alkynyl-coumarin complex, [Au{7-(prop-2-ine-1-yloxy)-1-benzopyran-2-one}-
(DAPTA)] (1), was synthesized and the formation of long luminescent fibers in solution was characterized
via fluorescence microscopy and dynamic light scattering. The fibers presented strong blue and green
luminescence, suggesting that the gold(I) in the complex increased intersystem crossing due to the heavy
atom effect, resulting in a significant increase in triplet emission. The X-ray structure of the fibers indicates
that both aurophilic, π–π interactions and hydrogen bonding contribute to their formation in aqueous
solvents.
