Abstract:
Self-assembled monolayers of 2-anthracenethiol and 2-naphthalenethiol on gold (111) were irradiated with low-power UV light. Scanning tunneling microscope images recorded in situ show unusual structural changes. In the case of 2-anthracenethiol, structures measuring 4-7 nm wide and 30-40 nm in length are formed. Images taken 10 min after irradiation ceased to show further surface reorganization. With 2-naphthalenethiol SAMs, smaller structures form upon irradiation, which subsequently revert to resemble the original structure after time.
