New photo-CORMs: Deeply-coloured biocompatible rhenium complexes for the controlled release of carbon monoxide
摘要:
Air- and water-stable rhenium carbonyl complexes are investigated as CO-carriers for studying the light-dependent release of small amounts of carbon monoxide under physiological conditions. The reported very low quantum yields are in a suitable range for studying potential applications as photochemical CO-releasing molecules (Photo-CORMs) without rapidly reaching cytotoxic levels of carbon monoxide. Preliminary results on bio-compatibility and selective uptake of the compounds into human colon carcinoma cells (Caco-2 cell line) are described. (C) 2015 Elsevier B.V. All rights reserved.
Synthesis and Characterization of Novel Re(BIAN)(CO)3Cl Derivatives Including the First Example of a Water-soluble Tricarbonyl Rhenium(I) Complex with Bis(imino)acenaphthene Ligands
摘要:
我们制备了一系列以双(亚氨基)苊(BIAN)分子为 p 受体配体的羰基氯化铼(I)配合物,并通过各种光谱技术对其进行了表征。在所描述的新化合物中,有一种深色的水溶性羰基铼衍生物是一个引人注目的例子。此外,还报告了该系列 BIAN 化合物的晶体结构,证实了氯配体位于三羰基铼(I)中心的位置。在芳基亚氨基亚基的正交位置上带有笨重取代基的 BIAN 配体的情况下,发现了卤化物配体在溶液中发生交换的证据,这被认为对催化应用具有重要意义。本文简要讨论了我们的研究结果对光催化二氧化碳还原和水溶液中可控释放气体传递剂一氧化碳领域的影响。
