The magnetic measurements reveal that compounds 24 exhibit antiferromagnetic properties. TGA results indicate compounds 1 and 4 have good thermostability with the critical temperature of 375 °C. 展开 关键词: Heterometallic coordination polymers Lanthanides Lanthanide contraction Magnetic properties ...
摘要: In this chapter, an attempt has been made to explain the role of ultrasonication in the synthesis of pure nanoparticles and nanoparticle-loaded polymers (i.e., hybrid). Ultrasound acts as an...DOI: 10.1007/978-981-287-470-2_17-1 ...
These prepolymers were fully characterized by 1H-nuclear magnetic resonance (NMR), matrix-assisted laser desorption/ionization time- of-flight mass spectrometry (MALDI-TOF MS) and size exclusion chromatography (SEC). The monocyclic prepolymer with an ethynyl group (1a, 2.4– 2.5 kDa) was subjected...
in Fig.1d-Iand Supplementary Fig.2. Notably, the present CNS material has a low optical bandgap, strong red photoluminescence, and complex slow magnetic ordering behavior at low temperatures. This helical carbon material offers a chance for the investigation of its physical and magnetic properties....

Metal organic frameworks (MOFs) have exceptionally high surface areas and porosity, and have been used for penetration, accumulation and separation of various species, such as heavy metals, radionuclides, and other toxic chemicals from both gas and liquid phases[6-11]. Since the magnetic properties...
We then modified reversibly immobilized proteins with protein-reactive ATRP initiators and, after ATRP, we released and analyzed the protein polymers. The activity and stability of PARIS-synthesized and solution-synthesized conjugates demonstrated that PARIS was an effective, rapid, and simple method to...
The synthesis of polymers with on-demand sequence structures is very important not only for academic researchers but also for industry. However, despite the existing polymerization techniques, it is still difficult to achieve copolymer chains with on-dem
