分子转动可以引发多种特殊的物理化学性质，从而表现出宏观的特殊性能，如：电学、储热、催化及光学等。近来，本课题组在分子转动引发可逆相变及其性质方面做了一系列的工作，如：客体水分子的转动引发铁电极化[1]。
Monodisperse trimetallic CoAgPd alloy nanoparticles(NPs)were synthesized by a controlled co-reduction of cobalt(Ⅱ)acetylacetonate,silver nitrate and palladium acetylacetonate in oleylamine at 90 ℃ usi
Noble metals are well-known for their surface plasmon resonance effect that enables strong light absorption typically in the visible regions for gold and silver [1,2].However,unlike semiconductors,nob
近年来锰-稀土异金属簇合物作为分子基磁体由于其独特的性能引起了人们的广泛关注[1]。相比于传统的无机磁性材料,分子基材料具有体积小、耗能小、结构多样等优点[2]。最近,我们合成出一种新的锰-稀土异金属六核簇合物：[Mn4Pr2(O)2(hmp)4(O2CPh)6(NO3)4]。该簇合物属于单斜晶系,P1 21/c1空间群。
Temperature is one of the most important parameters as it is a principal thermodynamic property.Among the techniques for measuring temperature,luminescence-based thermometers attract much attention be
Electrochemical energy conversion devices ranging from fuel cells to metal-air batteries demand effective electrocatalysts for oxygen reduction reaction(ORR)and oxygen evolution reaction(OER)[1].
由于巨大的比表面积,独特的电子效应和可控的几何形状,多金属纳米材料往往展现出特殊的光学性质、优异的催化性能等等。[1-3] 鉴于其性能对尺寸、结构和形状的高度依赖性,对上述参数进行有效调控具有重要意义。相对于广泛研究的生长控制,腐蚀方式的可控调控相对报道较少,尤其是在一维金属纳米颗粒上。[4,5] 这里,我们以金基纳米棒为例,通过不同的腐蚀方式,制备出多种新颖多金属纳米结构。
Synthesis of biaryl compounds through C-H bond activation of arylation has been the focus and frontier research in the field of green chemistry and Pharmaceutical Synthesis.
Direct construction of C-C bond from inert C-H bond is a highly efficient and sustainable strategy in synthesis of arylated indoles due to no need of organometallic activating groups.
苯丙氨酸二肽分子(FF)拥有易于修饰和控制,多重刺激响应性和良好生物相容性等特殊性质而被广泛地应用于纳米功能材料和生物传感等领域[1,2]。本文在FF分子上进行修饰,首次引入α氨基酸(组氨酸,His)构建成组氨酸-苯丙氨酸二肽分子(His-FF)。
