报告摘要：
abstract：Hybrid metal halides belong to a class of emerging optoelectronic materials that are highly tunable in structure and properties. The success of halide perovskite phases for solar cells and light-emitting diodes, has prompted us to explore deeper potentials and more applications for this large family of materials. Recently, the idea of utilizing chiral organic cations as either ligands or templates to self-assemble with emissive metals becomes a key direction which our group has been working on. Highly emissive transition-metal halides with non-centrosymmetric structures based on Mn(II) and Cu(I) are synthesized and characterized. The successful chirality transfer to the inorganic backbone prompt us to investigate their chiroptical properties, such as circular dichroism, circular polarized light emission and second harmonic generation. Alternative metal options such as Ge, Bi and Sb are of great interests because of their environmentally benign characteristics. Taking advantage of the sterically active lone pair of germanium and the interplay of ionic radii, we have developed a series of hybrid germanium perovskite and their two-dimensional derivatives, and investigated the structure-non-linear-optical-properties correlations. Using a series of cationic ligands with oxygen atom as the coordination site with alkali metals, we have synthesized a series of non-centrosymmetric double perovskite derived halides with non-centrosymmetric structures. Our work exemplifies the flexible chemical tools in pursue of new functional materials for a wide variety of applications.
