Urgent Replacement of UV-vis/near-IR Spectrometer

紫外可见/近红外光谱是一种重要的技术，用于量化分子和材料的颜色，研究反应机制，以及量化溶液中的结合和聚集。拟议的紫外可见/近红外光谱仪将用于溶液中和薄膜中的各种化合物和材料的变温研究。支持的研究实例包括用于感测溶液中分析物的超分子、基于虹彩纤维素薄膜的光子传感器、大环金属络合物、用于太阳能收集的光敏分子以及用于杀死病毒和细菌的光敏聚合物。该工具将由各种各样的本科生、研究生和博士后研究员使用，并将支持多个研究小组中许多受训人员的研究活动。它将提供宝贵的实践培训，这对有机和无机化学研究人员至关重要。

UV-visible / near-IR spectroscopy is an important technique to quantify the colours of molecules and materials, to study reaction mechanisms, and to quantify binding and aggregation in solution. The proposed UV-vis / near-IR spectrometer will be used for variable-temperature studies of diverse compounds and materials in solution and as thin films. Examples of research to be supported include supramolecules for sensing analytes in solution, photonic sensors based on iridescent cellulose nanocrystal films, macrocycle-metal complexes, photoactive molecules for solar energy harvesting, and photoactive polymers for killing viruses and bacteria. The instrument will be used by a diverse set of undergraduate students, graduate students and post-doctoral fellows, and will support the research activities of many trainees in multiple research groups. It will provide valuable hands-on training, which is essential for researchers in organic and inorganic chemistry.
