Light-Addressable 2D Covalent-Organic Framework Semiconductors

Among the most prominent fields of contemporary materials and chemical sciences is the design and synthesis of synthetic porous materials. Among these materials, reticulated crystalline 2D covalent organic frameworks (COFs) are progressively taking a prominent role. These porous polymers consist of entirely organic building blocks interconnected in 2D structures, showcasing considerable potential in applications such as catalysis, molecular sieving, gas storage, and, more recently, electronics. The synthetic adaptability of COFs, achievable through a diverse array of well-established organic reactions, enables the customization of their composition and properties using dynamic covalent chemistry approaches and post-synthetic modification. This synthetic flexibility positions them as ideal candidates for the production of cost-effective, flexible devices. Despite their versatility, most of these structures remain “passive”, which renders their function predefined by the choice of the building blocks used for construction of the interconnected network. Yet, the ability to remotely control the properties of these materials could open avenues for responsive device fabrication and drive the advancement of adaptive materials. Among the various types of stimuli, light offers opportunities for non-invasive, waste-free control over the properties of the materials with the highest spatial temporal precision. Consequently, the aim of the LAD2DCOFs project was to develop photoswitchable semiconductive 2D COFs, establishing a foundation for future reconfigurable and adaptive devices. By integrating photoswitchable moieties into porous solids, this research places a primary focus on the understanding of the behavior of the photoswitchable elements in the porous scaffold, with the ultimate goal of leveraging fundamental studies for the development of new materials.

Цел на проекта

LA2DCOFS will offer an extremely talented and promising young researcher with a PhD in chemistry and an extraordinary track record a world-class training throuDiscovery and development of two-dimensional (2D) semiconductors marked a milestone in modern condensed matter physics and material science. These structures exhibit unique set of properties and excel in almost every aspect of the device performance over their three-dimensional counterparts. Among these materials, recently developed semiconducting 2D covalent-organic frameworks (2D COFs) received a significant attention owning to their exceptional environmental stability, tunability, processability and modular synthesis. However, to date, these structures remain passive, which limits their potential applications. To address this challenge, this proposal describes our plans to develop light-responsive 2D COF-based semiconductors. More specifically, we will integrate light-responsive molecules – dithienyl ethenes (DTEs) – in the backbone of the crystalline imine-linked framework which will allow us to gain a remote control over their performance in electronic devices with light stimulus. We will fabricate a library of networks, consisting of various likers and DTEs and validate their performance and light-responsive function in field-effect transistor devices. Furthermore, the fabricated structures will be modified by post-synthetic reactions on the network linkages to further improve their charge transport properties and thus performance in proof of a concept device. Finally, we will integrate several DTEs with distinct electronic properties into one framework, thus creating a multivariate semiconductive 2D COFs, which will allow us to gain a simultaneous photocontrol over several parameters of the electronic devices. Overall our efforts, if successful, will result in fabrication of unprecedented semiconducting materials and will pave the way for the development of future technologies based on these materials.
