Axial N Disrupt d –π Conjugation of Asymmetric Fe─Cu Dual‐Atom Enhances CO 2 Electroreduction

ABSTRACT Precise spin‐polarization modulation of electronic structures in dual single‐atomic sites (DSAS) is critical yet challenging for boosting electrocatalytic CO 2 reduction reaction (CO 2 RR). Here, we report a Fe 3 d ‐orbital spin‐polarization regulation strategy through c...

Antioxidant Benzophenones and Biphenyls from an Endophytic Fungus Penicillium sp. QM-4

The endophytic fungi from plants are recognized as a valuable source of structurally diverse secondary metabolites with intriguing bioactivities. Three previously undescribed compounds, including two benzophenones, 2-(2,6-dihydroxy-4-methylbenzoyl)benzoic acid (1) and 2-(2,6-dihy...
