A new bis-heteroleptic Ru complex () with iodotriazole as the anion binding group along with the attached pyrene moiety is developed to investigate anion sensing properties and the origin of its selectivity toward a particular class of anions. Selective sensing of phosphates over other anions in both the solution and solid states by is clearly evident from the perturbation of the absorption band and a large degree of amplification of MLCT emission band in the presence of phosphates. Importantly, macroscopic investigation such as Scanning Electron Microscopy (SEM) and Dynamic Light Scattering (DLS) indicated the formation of supramolecular architecture in the presence of dihydrogen phosphate via halogen bonding interaction and π-π stacking of pyrene moieties. Such macroscopic property is further corroborated by solution and solid state spectroscopic studies, e.g., H-DOSY NMR, single crystal X-ray crystallography, and solid state photoluminescence (PL) spectroscopy.
开发了一种新的双杂配钌配合物（），其阴离子结合基团为碘三唑，以及附着的芘部分，以研究阴离子传感性能及其对特定一类阴离子选择性的起源。在溶液和固态中，通过吸收带的微扰以及在存在磷酸盐的情况下 MLCT 发射带的大幅度放大，明显清楚地表明了对磷酸盐的选择性传感。重要的是，宏观研究，如扫描电子显微镜（SEM）和动态光散射（DLS）表明，通过卤键相互作用和芘部分的π-π堆积，在存在二氢磷酸盐的情况下形成超分子结构。这种宏观性质进一步得到了溶液和固态光谱研究的证实，例如，H-DOSY NMR、单晶 X 射线晶体学和固态光致发光（PL）光谱学。
