In this work, a visible light-mediated [3+2] cycloaddition reaction between azide molecule and benzocycloheptene(BC7) terminated Au (111) surface was investigated. Exposure of the BC7 to photocatalyst and visible light facilitated the double bond isomerization of benzofused-cycloheptene, Z-BC7 to a strained and kinetically unstable alkene, E-BC7 to undergo cycloaddition with azide molecule to form triazoline ring structure. The reaction progress was monitored via attenuated total reflectance-Fourier transform infrared (ATR-FTIR). The strategy reported here offers spatial and temporal control of functionalization along with catch and release mechanisms due to the cleavable nature of the linker.
