Supramolecular transformations of coordination cage or capsule have received much attention recently,which help elucidate this natural self-assembly behavior in biological systems.The current study describes the first supramolecular transformation of titanium-organic coordination capsule triggered by phenol (and H3PO3).The structural alterations are accompanied by the reconstruction of 5-coordinated Ti centers to 6-coordinated ones.Meanwhile,different amounts of encapsulated phenol guest molecules can be identified,dependent on the sizes of the obtained cavities.In addition,they display much better visible light absorption and air stability than the isopropanol stabilized ones.

The photoisomerization properties of azo derivatives have been widely used in the fields of materials and biology.One serious restriction to the development of functional azo-based materials is the necessity to trigger switching by UV light,which damage t
Hydrogen sulfide (H2S) is a signaling molecule that plays important roles in biological systems.The exploration of H2S as a new drug release trigger and its related fluorescent theranostic system is crucial for cancer bio-imaging and therapy.Herein,we des
以江苏省丰县为例,采用核密度、标准差椭圆等方法,探讨19902018年淮海经济区县域制造业结构演替时空异质性特征.淮海经济区县域制造业的行业结构呈现由资源劳动密集型向技术密集型演变,民营企业主导所有制结构演替,呈现大中型企业规模优势渐显、小型企业主体地位持续下降的趋势.研究期内县域优势主导产业快速演替,但近年来产业结构演替缓慢,发展后劲不足.丰县制造业分布呈现由以县城为中心的核心边缘格局,逐步演化为以县城为核心、以主要交通干线为依托、以重点镇为节点的“一核一轴多心”的空间格局.
