含二茂铁基的锌配合物的结构及其生物活性 总被引:1,自引:0,他引:1
合成了4个含二茂铁基的锌配合物[Zn(FcCOO)(phen)2]ClO4·FcCOOH (1)(FcCOO=二茂铁甲酸根,phen=1,10-邻菲咯啉),[Zn(FcCOO)(phen)2]·ClO4·H2O (2),[Zn(FcCOO)(FcCOGly)(phen)]·C2H5OH (3)(FcCOGly=二茂铁甲酰化甘氨酸)和[Zn(FcCOGly)2(phen)]·CH3OH (4)。用X-射线单晶衍射测定了配合物的晶体结构。对4个配合物的生物活性进行了初步研究,发现配合物的抗菌活性与配合物的配位键强度及phen含量有一定的关系。 相似文献

Polarization-Insensitive Narrow Band Filter with a Symmetrical Metal-Cladding Optical Waveguide 下载免费PDF全文
We demonstrate the promising configurations that permit very narrow spectral filtering. The waveguide filter consists of a glass slab with an anomalous thickness of about 500μm, which is sandwiched between two pre-coated metal films. By using the free-space coupling technique, a polarization-insensitive and tunable notch filter with a spectral bandwidth as narrow as 0.08nm has been obtained due to the excitation of ultrahigh-order modes of the symmetrical metal-cladding optical waveguide. 相似文献
