J. Hu et Dl. Mattern, Ferrocenyl derivatives with one, two, or three sulfur-containing arms for self-assembled monolayer formation, J ORG CHEM, 65(8), 2000, pp. 2277-2281
Self-assembled monolayers of electroactive molecules can form on gold elect
rodes if the molecules include a sulfur-containing group to coordinate with
the gold surface. We have prepared a molecule with a tripod of sulfur grou
ps that has the potential of fixing the geometry of the molecule relative t
o the gold surface. The target (3) contained the good one-electron donor fe
rrocene connected through a benzene spacer to an isobutane tripod, with eac
h arm of the,tripod ending in a methylthio group. Analogous compounds with
one (1) and two (2) coordinating arms were also prepared.
