Abstract:
As the world moves towards a more sustainable future, the development of innovative materials that do not rely on precious metals or critical raw materials and can be utilized in a range of sustainable applications is becoming increasingly important. This is particularly true for key technologies such as electronics, optoelectronics and quantum devices as well as energy storage systems, which require new materials. In this seminar, we will introduce organic 2D crystals as a new class of sustainable materials that have exhibited unique properties and potential applications in a range of technological devices.
We will discuss the recent advances in the bottom-up synthesis of organic 2D crystals, including 2D conjugated metal-organic frameworks, 2D conjugated polymers, and covalent-organic frameworks, as well as the single-layer to few-layer 2D polymers as well as their 2D van der Waals heterostructures. On-water surface chemistry will be highlighted as a robust synthetic platform for many such materials. The resulting organic 2D crystals possess tailorable conjugated building blocks and conjugation lengths, tunable pore sizes and thicknesses, as well as impressive electronic structures. We will demonstrate the particular promise of this class of materials in view of their excellent properties in electronics, optoelectronics, magnetism, and sensors. The relevance of these materials for quantum phenomena and quantum technologies will be discussed. Additionally, we will discuss 2D polymer-based membranes with tunable pore size and pore arrays, which have the potential for technologies such as batteries, osmotic energy generation, and separations. By leveraging the unique properties of organic 2D crystals, we can build a sustainable future that meets the needs of society. The potential of organic 2D crystals for a variety of sustainable technologies and devices, as well as their potential as quantum materials, makes them a promising candidate for building a sustainable future.
