SUMMARY:Inorganic Chemistry Student Exit Talk: Shuaijing Du
DESCRIPTION:Shuaijing Du of the Duan Research Group \nFlyer: Shuaijing Du Student Exit Talk Flyer \nTitle: Introducing Chirality into Hybrid Superlattices \nAbstract: I will present recent results on two different projects\, with the common theme of introducing chirality into hybrid superlattices. 1: Modular assembly of a library of hybrid superlattices. Hybrid superlattices\, composed of two-dimensional atomic crystals (2DACs) and self-assembled molecular layers\, provide a platform for synergizing the rich physical properties of solid-state 2DACs with customizable molecular functionalities. In this project\, we develop a modular electrostatic co-assembly approach for synthesizing over 50 hybrid superlattices from a diverse set of 2DACs and molecular building blocks. We demonstrate that in addition to amines\, chiral amino acids and coordination complexes can also assemble with exfoliated MoS2 into hybrid superlattices\, incorporating optical chirality into the hybrid superlattices. 2: Construction of chiral hybrid superlattices with monoatomic platinum layers. Compared with layered materials such as graphite and transitional metal dichalcogenides with highly anisotropic in-plane covalent bonds\, freestanding metallic two-dimensional (2D) films with atomic thickness are intrinsically more difficult to achieve. This study introduces stabilized monoatomic Pt layers by forming a chiral hybrid superlattice structure with self-assembled chiral carboxylic acid ligand layers. Circular dichroism (CD) spectra of the chiral hybrid superlattices show clear CD signals distinct from the chiral carboxylic acids themselves.
