Ein kovalentes organisches Gerüst (COF) aus Benzothiadiazolen mit effizienter Zwei‐Photonen‐induzierter Emission wurde von X. Z. Zhang und Mitarbeitern synthetisiert, wie in ihrem Forschungsartikel auf S. 10173 beschrieben wird. Die einzigartige Struktur des COF schwächt π‐π‐Stapelwechselwirkungen zwischen den Schichten ab und vermeidet eine aggregationsinduzierte Emissionslöschung. Das Material sorgt...
Fluorescent materials exhibiting two‐photon induction (TPI) are used for nonlinear optics, bioimaging, and phototherapy. Polymerizations of molecular chromophores to form π‐conjugated structures were hindered by the lack of long‐range ordering in the structure and strong π–π stacking between the chromophores. Reported here is the rational design of a benzothiadiazole‐based covalent organic framework...
