2D Conjugated Polymers: π-Conjugation, Nontrivial (Opto)Electronic and Magnetic Properties
The project aims to explore 2D CPs for achieving high charge carrier mobilities, narrow band gaps, prolonged charge lifetimes, and strong magnetic couplings between the monomers. The aim is to exfoliate layered 2D conjugated polymers (CPs) into solution-processable nanosheets, and integrate them into prototype devices for achieving structure-property relationship and high charge mobilities in organic transistors
1st Funding Period
2D Conjugated Polymer Frameworks: Robust Linkages, and Novel Polycondensation Reactions
The project will focus on the solvothermal synthesis of 2D conjugated polymer frameworks (CPFs) with a skeleton of monomers covalently linked by π-conjugated C=C bonds. Such 2D CPFs would enable a promising class of semiconducting materials, and offer band gap engineering by varying the extent of π-conjugation in incorporated building blocks. In this respect, three methodologies based on the reversible and/or semi-reversible polycondensation reactions will be explored: Knoevenagel reaction, Horner-Wadsworth-Emmons reaction and vinylation through homo-coupling of 1,3-dithiolan-2-one derivatives. Furthermore, understanding on bond formation efficiency, reaction mechanism, nucleation and growth, chemical/electrochemical exfoliation as well as the electronic/ geometric properties will be taken as key foci.
