Nitrogen‐Site Isomerism Unlocks Exciton Dissociation in Vinylene‐Linked COF‐Based Photocatalysts

EcoEnergy, EarlyView.
Two regioisomeric vinylene‐linked covalent organic frameworks (COFs) constructed from diazine units with different nitrogen positions are developed for photocatalytic hydrogen evolution reaction (HER). Although structurally similar, the isomeric COFs exhibit distinct electron distribution and charge‐separation behaviors, leading to a more than twofold ...

Click Bioconjugation of Aza‐BODIPY Fluorophores to LfcinB Peptides for Improved Biocompatibility

European Journal of Organic Chemistry, EarlyView.
Click bioconjugation attaches NIR aza‐BODIPY fluorophores to LfcinB‐derived anticancer peptides via CuAAC and thiol‐maleimide chemistry. Conjugates exhibit improved predicted solubility while retaining strong NIR absorption (703–730 nm). Peptide‐aza‐BODIPY conjugates induce apoptotic morphology in HeLa cancer cells.
