In a recent article published in Nature Chemistry, an international team of researchers successfully applied cyclophane chemistry, for the first time, to graphene nanoribbons (GNRs) system. Their study demonstrates that this cyclophane-based shielding strategy not only sterically shields the π-conjugated surface of GNR but also imparts internal strain, enabling singly dispersed GNRs while simultaneously modulating their optoelectronic properties, thereby providing a generalizable strategy for engineering solution-processable GNRs compatible with quantum device applications. mehr

Scientists at the Max Planck Institute of Microstructure Physics demonstrate broadband integrated photodetectors for visible and near-infrared photonic circuits, featuring low dark currents, high-speed operation, and avalanche mode capability. mehr

An international team from the Max Planck Institute for Microstructure Physics, the Krembil Brain Institute, the University of Toronto, and Advanced Micro Foundry demonstrates a silicon-photonics neurotechnology that integrates photostimulation, electrical recording, and drug delivery. mehr

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. mehr

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. mehr
