ESR

The coloration behavior of the inorganic/organic hybrids prepared from polydimethylsiloxane (PDMS) and chemically modified metal alkoxides was investigated by ultraviolet-visible (UV-VIS), X-ray photoelectron (XPS) and electron spin resonance (ESR) spectroscopies. Although the hybrids were transparent in the visible region, a broad absorption was observed from the visible to UV regions, leading to a color from yellow to wine-red. The color and the absorption edge of the hybrids depend on the inorganic components derived from metal alkoxides.

含有生物活性金属的金属-有机骨架( MOFs )可能通过金属-配体键将金属离子或配体释放到介质中，对各种微生物表现出活性。但是，为了成功的临床应用，需要在较长时间内控制释放，以避免因金属离子过量而产生毒性。近年来，具有缓释能力、孔隙率和结构柔性的铜基MOFs ( Cu- MOFs )表现出抗菌性能。为了开发可再生的生物医用材料，我们将含有戊二酸和1，2 -双( 4 -吡啶基)乙烯配体的Cu - MOF固定在生物相容的聚二甲基硅氧烷( PDMS )中，在25   ° C下通过硅氢加成反应固定在PDMS表面。此外，PDMS @ Cu - MOF保持了PDMS的物理和热性能，对小鼠胚胎成纤维细胞的毒性较低。PDMS @ Cu- MOF由于其抗菌性能和低细胞毒性，在植入物、皮肤病治疗、伤口愈合、药物输送等方面具有潜在的药用应用前景。
