Converting 1D Conjugated Polymers into Functional 2D Materials
The project aims in creating 2D functional polymeric materials by converting 1D CPs into 2DMs which will result in materials that combine features of 2D COFs and MOFs in a unique way. Linkers with additional functions will be integrated by a second type of (dynamic) bonding. It is expected to achieve by that approach a specific ordered 2D arrangement of donor(D)-acceptor(A) moieties, resulting in unprecedented optoelectronic properties e.g., high luminescence, due to electronic interaction of the 1D part with the linker moieties. In addition, the incorporation of redox active and ion conductive units will allow to explore specific catalytic effects and combination of electronic and ionic conductance.
1st Funding Period
2D Organic/Metal Halide Materials
The project will target at the direct growth of atomically thin sheets of 2D layered perovskites (mainly lead halogenides, RNH3PbX3) using solution as well as surface templating approaches and various modulating ligands. The key challenge is to control the growth of defined monolayers (< 2 nm thickness) but also of thin flakes and films of stacks with up to 10 monolayers. Next, the defined 2D perovskite layers will be integrated with semiconducting organic ligands as well as with other 2D layered (semi)conductor materials starting with graphene, 2D polyaniline and continuing with other 2DMs developed within the CRC, such as c-MOFene.
