The linear-chain polymer {Tl[Au(C6Cl5)2]}n, 1, reacts in the solid state and in solution with different volatile organic
compounds such as tetrahydrofuran, acetone, tetrahydrothiophene, 2-fluoropyridine, acetonitrile, acetylacetone, and
pyridine. Solid-state exposure of 1 to vapors of the above VOCs produces a selective and reversible change in its
color that is perceptible to the human eye and even deeper under UV irradiation, allowing 1 to function as a sensor
for these VOCs. Heating the samples exposed to the VOCs for a few minutes at 100° C regenerates the original
