In a recent article published in Angewandte Chemie International Edition, researchers from TU Dresden and the Max Planck Institute of Microstructure Physics reported the successful synthesis of graphene nanoribbons incorporating [18]annulene nanopores, together with a nonporous GNR of identical width. Their study demonstrates that nanopore incorporation effectively tunes the electronic properties by enlarging the bandgap, reducing charge-carrier mobility, and modulating exciton dynamics, thereby establishing a versatile strategy for the design of porous graphene nanostructures with tailored opto-electronic characteristics. more

Researchers from the Max Planck Institute of Microstructure Physics, Technische Universität Dresden, the Max Planck Institute for Polymer Research, and collaborating institutions have developed a new class of donor-acceptor two-dimensional conjugated polymers with record-high charge carrier mobility and ultranarrow band gaps. The work establishes diketopyrrolopyrrole (DPP)-based two-dimensional poly(arylene vinylene)s as high-performance organic semiconductors. more

In a recent study published in Nature Chemistry, an international team of researchers reports a new Mannich-elimination synthetic methodology for the construction of single-crystalline two-dimensional poly(arylene vinylene) (2D PAVs) covalent organic frameworks. The team elucidates reversible C=C bond formation driven by Mannich-elimination mechanism, and showcases the synthesis of eleven highly crystalline 2D PAVs converted from eight 2D polyimine precursors. This work further demonstrates that crystallinity has a large impact on the charge transport properties, as exemplified by benzotrithiophene-based honeycomb 2D PAVs exhibiting charge mobilities 10 times greater than the amorphous 2D PAVs or their 2D polyimine counterparts. more

In a recent article published in Nature Communications, researchers from TU Dresden and the Max Planck Institute of Microstructure Physics reported a side chain-induced chirality amplification (SICA) strategy that enables the synthesis of highly crystalline and conductive chiral 2D c-MOFs with tunable chirality and record-high spin polarization of up to 96.9%. This approach represents a significant advancement for designing chiral 2D crystalline materials with high conductivity and high spin polarization, highlighting the significant potential of chiral 2D c-MOFs in chiral electronics and spintronics. more
