摘　　要：On-surface Ullmann-type reaction,or the dehalogenated coupling,is arguably the most pivotal reaction in on-surface synthesis for the fabrications of carbon nanostructures.Hitherto,the vast majority of works rely on activating the C-Br bond of aryl bromide which has a moderate bond dissociation energy.The C-Cl bond of aryl chloride has a higher dissociation energy and requires much higher thermal energy to break the bond.In this study,we have explored the on-surface photo-induced dechlorination and achieved the activation of three distinct aryl chlorines on the Au(111)surface with mild temperatures.This work enriches our understanding of on-surface photo-induced reactions and highlights the potential of photochemistry in realizing unconventional reactions.
