Understanding Quantum Effects in 2D Polymeric Systems
Abstract
Major Goals: Two-dimensional polymers (2DPs) consist of covalently bonded molecular tiles (ligands) that extend across two dimensions to form layered van der Waals (vdW) materials similar to graphene and other 2D inorganic materials (MoS2, WSe2, h-BN, etc.). While quantum effects are well-established for inorganic vdW solids, properties of 2DPs remain largely unknown. This is mainly due to difficulties in 2DPs sample preparation, characterization, as well as instrumentation inadequacies. Thus, studies are often restricted to simulations or thick polymers. However, true merits of 2DPs lie in two-dimensions when quantum effects become prominent. For example, theoretical studies predict and our preliminary experimental findings hint many exciting properties and quantum phenomena on 2DPs at the nanoscale. Precisely focused on these merits, the scientific objective of this Short Term Innovative Research (STIR) project is to enable, discover, and understand emergent optical and electronic behavior of optically active 2DPs. The project will systematically investigate material behavior of 2DPs from bulk to monolayers to capture quantum confinement effects. Studies will help to test theoretical predictions and unravel novel quantum phenomena at nanoscale. If successful, this research effort will 1) offer the first look at electronic, optical properties of 2DPs, 2) provide atomicresolution insight into crystallographic properties of 2DPs, and 3) establish how material behavior of 2DPs changes when quantum size confinement effects become dominant.
