Summary: A novel method using mechanochemical Ullmann-type reactions to promote direct aromatic ring knitting has been demonstrated to afford CPNs with high surface areas and mesoporous architecture under neat and ambient conditions. The versatility of this approach has been confirmed by successful construction of various CPNs and even highly crystalline graphite product, showing good electrochemical performance in lithium-ion batteries. This strategy expands the frontiers of CPN synthesis and provides new opportunities for their scalable applications.

Summary: The relationship between microstructure and performance in bimetallic nanoclusters was explored using coreless Au4Cu5 as a model. Compared to coreless monometallic nanoclusters, core-shell nanoclusters, and single atom catalysts, the coreless Au4Cu5/activated carbon catalyst exhibited higher activity and stability in the Ullmann C-O coupling reaction. The structure-activity relationship was successfully extended to other coreless bimetallic systems and could provide insights for designing bimetallic catalysts with well-defined performance.

Summary: We present a synthetic method for pyrrolizine-3-one derivatives and investigate their photophysical properties. These compounds are prepared through a series of reactions involving substituted pyrroles in one-pot, two-step oxidation, and intramolecular cyclization processes. The photophysical properties of the synthesized compounds are studied using UV-Vis and fluorescence spectroscopy in various solvents. The introduction of pyrrolyl substituents has a significant impact on Stokes shifts and quantum yield values.
