《金属-有机框架》专辑序言──金属-有机框架:新型多功能材料

<正>金属-有机框架是由金属离子与有机配体通过配位键形成的三维框架材料,是近几十年来配位化学领域中发展较快的新型多功能材料。自上世纪90年代以来,金属-有机框架的研究呈现空前的增长,目前已有大于20000例的金属-有机框架被报道。金属-有机框架可变的金属中心及有机配体使其结构与功能具有多样性。金属中心的选择几乎覆盖了所有金属,包括主族元素、过渡元素和镧系金属。而配体的选择,除了传统的氮杂环和羧酸类配体外,还可以引入一些官能团对其进行修饰,使已获得的金属-有     

Special issue on recent progress in organic electronics and photonics

正Organic electronic and photonic devices have received tremendous attention from both academia and industry because of their great promise for practical use as organic light-emitting diodes(OLEDs),organic solar cells(OSCs),organic field-effect transistors(OFETs),and chemical and biological sensors.During the past decade,remarkable pro-     

Laboratory accreditation in New Zealand

A voluntary system for the registration of testing laboratories was established in New Zealand in 1972. It requires laboratories to meet specific standards, maintain adequate methods manuals and records and exhibit competence in the test methods for which registration is granted. The system also authorizes the endorsement of test documents.     

Chemical metrology in New Zealand

Recent developments in international trade will have a significant impact on New Zealand’s measurement infrastructure, especially for chemical metrology. This article describes the background to these developments and outlines the activities of the Measurement Standards Laboratory, New Zealand’s National Metrology Institute, in response to these developments.
