Synthesis and Characterization of New Transition Metal phosphate halides [PDF]
, 2016 随着含氟磷酸铁锂在二次锂离子电池正极材料中的应用，含氟聚阴离子型化合物受到了人们的关注，但是在合成化学上多个阴离子基团的引入存在一定的难度，使得含氟或卤素磷酸盐化合物的数目并不多，结构化学亟待丰富。同时多阴离子基团与过渡金属元素之间的协同作用规律性也有待进一步探索。因此本文旨在以含氟、含氯和含氟氯的过渡金属磷酸盐为研究对象，利用氯化物盐类自带的结晶水而尽可能少加水或不加水的水热法，探索合成新晶体，进一步丰富该类化合物的结构化学，探讨氟和氯在晶体结构中的作用，并研究其热稳定性或磁性等方面的性质 ...

Synthesis, Crystal Structures and Properties of Silver Clusters [PDF]
, 2015 银簇合物的结构复杂，功能多样，受到人们的广泛关注。这类化合物的合成往往涉及多个组分(多金属中心和多种配体)的有序结合，具有极大的挑战性。多数银的簇合物见光易分解，提高其稳定性是一项重要的工作。前期的研究表明，采用多因素控制的方法，选择具有保护功能的炔银或硫银作为前驱体，通过内嵌阴离子模板、引入外围抗衡阴离子等手段，可以控制合成一系列结构新颖的高核银簇合物。随着对于银簇合物研究的不断深入，人们把关注的焦点逐渐转移到对其性质调控和功能改性上。因此，本文选定银簇合物最重要的特点之一—发光性质，作为主要研究对象。
