Multiswtichable Two-dimensional Covalent Organic Framework-based Optoelectronics

MS2DCOFO will offer a highly talented and promising young researcher with a PhD in chemistry and an outstanding track record a world-class training through research in the cross-disciplinary, supra-sectoral and burgeoning field of multifunctional 2D semiconducting covalent organic frameworks (COFs). MS2DCOFO’s overall mission is to coach the fellow to become a mature and independent scientist and to prepare him for a leading position in academia or industry in Europe. Organic field-effect transistors are crucial elements for the fabrication of flexible, wearable, and biocompatible electronic devices. As miniaturization is approaching its limits, bringing an end to Moore’s law, beyond-CMOS devices, “More-than-Moore” technologies aimed at functional diversification are emerging as technologically viable strategy to boost the data storage capacity in tomorrow’s digital electronics. 2D COFs, as crystalline porous organic polymers built by covalently connecting organic building units, represent ideal platforms to incorporate simultaneously different switchable units into a given 2D skeleton with a atomically precise and robust structure. Thus, on the long term, multiresponsive semiconducting 2D COFs can become crucial components in neuromorphic devices and synaptic arrays to meet the present and future requirements of higher computational density that cannot be achieved by scaling down CMOS transistors. In this framework, the making of multiresponsive semiconducting 2D COFs represents a grand challenge that can offer a major technological advancement for next-generation electronic devices. Towards this ambitious goal, we will first design and synthesize multiresponsive 2D COFs, whose switchable properties and stabilities will be carefully characterized. The related high-quality 2D COF films fabricated via interfacial, in-situ solvothermal, or exfoliation methods, will be integrated and tested into multifunctional semiconducting devices for complex logic operations.
