Recently, synthetic efforts have been directed toward the
preparation of polymeric materials with special optico-electronic
properties.1 Some of these materials are sensors for volatile organic
compounds (VOC).2 Materials that show appreciable selectivity and
tunable changes of color or emission in the presence of VOCs are
of particular interest.3 Here we report on a luminescent, polymeric,
semiconducting gold-thallium complex with a solid-state structure
that permits reversible interactions and related color changes with
a variety of VOCs.
By reacting equimolar quantities of [NBu4][Au(C6Cl5)2] with
TlPF6 in tetrahydrofuran, the compound {Tl[Au(C6Cl5)2]}n, 1, is
obtained as a pale yellow solid.4
