	abstract = {Abstract Ligand-induced surface restructuring with heteroatomic doping is used to precisely modify the surface of a prototypical [Au$_{2}$$_{5}$(SR{\textonesuperior})$_{1}$$_{8}$]$^{-}$ cluster (1) while maintaining its icosahedral Au$_{1}$$_{3}$ core for the synthesis of a new bimetallic [Au$_{1}$$_{9}$Cd$_{3}$(SR{\texttwosuperior})$_{1}$$_{8}$]$^{-}$ cluster (2). Single-crystal X-ray diffraction studies reveal that six bidentate Au$_{2}$(SR{\textonesuperior})$_{3}$ motifs (L2) attached to the Au$_{1}$$_{3}$ core of 1 were replaced by three quadridentate Au$_{2}$Cd(SR{\texttwosuperior})$_{6}$ motifs (L4) to create a bimetallic cluster 2. Experimental and theoretical results demonstrate a stronger electronic interaction between the surface motifs (Au$_{2}$Cd(SR{\texttwosuperior})$_{6}$) and the Au$_{1}$$_{3}$ core, attributed to a more compact cluster structure and a larger energy gap of 2 compared to that of 1. These factors dramatically enhance the photoluminescence quantum efficiency and lifetime of crystal of the cluster 2. This work provides a new route for the design of a wide range of bimetallic/alloy metal nanoclusters with superior optoelectronic properties and functionality.},

	abstract = {The zigzag-edged triangular graphene molecules (ZTGMs) have been predicted to host ferromagnetically coupled edge states with the net spin scaling with the molecular size, which affords large spin tunability crucial for next-generation molecular spintronics. However, the scalable synthesis of large ZTGMs and the direct observation of their edge states have been long-standing challenges because of the molecules{\textquoteright} high chemical instability. Here, we report the bottom-up synthesis of π-extended [5]triangulene with atomic precision via surface-assisted cyclodehydrogenation of a rationally designed molecular precursor on metallic surfaces. Atomic force microscopy measurements unambiguously resolve its ZTGM-like skeleton consisting of 15 fused benzene rings, while scanning tunneling spectroscopy measurements reveal edge-localized electronic states. Bolstered by density functional theory calculations, our results show that [5]triangulenes synthesized on Au(111) retain the open-shell π-conjugated character with magnetic ground states.},
