Coordination polymers of Au(I) and Ag(I) with thioguanosine

Reaction of Au(I) or Ag(I) ions with 6-thioguanosine in aqueous media produces coordination polymers in which the polymer backbone is a helical metal-sulfur chain. The polymers are chiral and luminescent. Reaction of mixtures of metal ions produces copolymers with optical properties intermediate between the Au and Ag homopolymers. The polymers are found to be labile in the sense that mixtures of homopolymers will revert to copolymers on a timescale of several hours. The dataset includes optical spectroscopy (absorption, emission and circular dichroism), atomic force microscopy, elemental composition and rheology.

Au(I)或Ag(I)离子与6-硫鸟嘌呤在水介质中的反应，可生成以螺旋状金属硫链为聚合物骨架的配位聚合物。此类聚合物具有手征性和发光特性。金属离子混合物的反应则产生光学性质介于金和银同聚合物之间的共聚物。研究发现，这些聚合物在性质上较为活跃，同聚合物混合物在数小时内将转变为共聚物。该数据集包括光学光谱（吸收、发射和圆二色性）、原子力显微镜、元素组成和流变学。
