application of nitroxide exchange reactions of surface‐bound alkoxyamines as a tool for reversible chemical modification of self‐assembled monolayers (SAMs). This approach is based on radical chemistry, which allows for introduction of various functional groups and can be used to reversibly introduce functionalities at surfaces. To investigate the scope of this surface chemistry, alkoxyamines with different

Site-selective immobilization of dyes and different protein recognizing entities at the surface of zeolite L crystals using mild radical nitroxide exchange reactions is reported. Exposure of these crystals to aqueous protein solutions leads to site-selective immobilization of proteins onto the crystals.
本研究利用温和的硝基自由基交换反应,在沸石 L 晶体表面对染料和不同蛋白质识别实体进行了位点选择性固定。将这些晶体暴露于蛋白质水溶液中可实现蛋白质在晶体上的位点选择性固定。

behaviour of cucurbit[6]uril was revealed in the ESR spectra of the nitroxides in the presence and in the absence of the host molecules, recorded at low temperatures. The experiments revealed that the mobilities of the nitroxides investigated are higher in the absence of the host molecule, a different behaviour compared with complexes with cyclodextrins. This behavior can be understood by taking into account
