| We have fabricated 1-adamantanethiolate self assembled monolayers (SAMs) on Au{111} and characterized them with scanning tunneling microscopy (STM). The adamantanethiolate SAMs are highly ordered and have less prominent domain boundaries than alkanethiolate SAMs, but the adamantanethiol molecules are easily displaced by other molecules both during and after SAM formation. This susceptibility to displacement makes theses molecules appealing as transient monolayers for the temporary protection of surfaces, or as backfilling agents on patterned surfaces. Using STM and lateral force microscopy (LFM) we have studied the molecular order and stability of micro-contact printed SAMs using adamantanethiolates and compared them to similar systems using alkanethiolates. |
