一种用于检测质子和金属离子的新型荧光装置 11-(9-anthracenylmethyl)-1,4,7-trithia-11-azacyclotetradecane (L),已被合成。此外,游离和质子化物质的光物理性质已通过 L 与甲磺酸的二氯甲烷溶液的吸收和荧光滴定进行了检查。L 对 Pd II 、Z n II 、Ni II 和 Co II 的配位性质已在溶液和固态中进行了研究。在吸收过程中观察到不同的行为
Novel tricarbonyl-molybdenum complexes bearing monoaza-trithia-macrocyclic ligands (LXR), [Mo(CO)(3)(LXR)] (X = 12 or 14, R = H), and [Mo(CO)(3)(L14(Py)) Mo(CO)(4)] have been synthesized to gain an understanding of the unique properties of macrocyclic ligands. X-ray structure analysis of [Mo(CO)(3) (L14(H))] has revealed that intra- and intermolecular hydrogen bonds existed and these interaction regulated CO bond lengths. In addition, vibrational spectroscopy indicates that a specific hydrogen bonding interaction affects the strength of the binding of carbon monoxide molecules to the metal. In case of using L14(Py), it is expected that dinuclear molybdenum complex was generated. (c) 2013 Elsevier B.V. All rights reserved.
