ToF-SIMS analysis of 1 on Au(111). a ToF-SIMS spectrum showing the molecular weight of positive ions (coverage of Br-TPP: ~0.5 ML). M1: molecular weight of divergent cross-coupling product 1; MCR: molecular weight of cross-coupling product of one Br-TPP with one ICBP; MTPP: molecular weight of debrominated product of Br-TPP. b Experimental and simulated isotopic distribution of [M1]+ ions of 1
