Irradiation sensitivity of self-assembled monolayers with an introduced "weak link"

The irradiation sensitivity of n-alkanethiolate SAMs can be enhanced by the incorporation of an irradiation-sensitive functionality as a predetermined breaking point into the alkyl chain. Following this general strategy, several different sulfur-derived functional entities with a variable position i...

Zusammenfassung:The irradiation sensitivity of n-alkanethiolate SAMs can be enhanced by the incorporation of an irradiation-sensitive functionality as a predetermined breaking point into the alkyl chain. Following this general strategy, several different sulfur-derived functional entities with a variable position in the alkyl chain were tested. In some cases, the incorporation of these entities resulted in a noticeable enhancement of the irradiation-induced desorption (by about 30%), even though the chains were not exclusively cut at the position of the incorporated group, but the scission events related to the "weak links" were just added to those in the alkyl matrix. The position of the incorporated group along the alkyl chain was found to be most essential for its performance as a weak link; the enhancement of irradiation-induced desorption was observed only when the groups were placed close to the SAM-ambient interface
