Dendritic thiol is a kind of molecule with special functional group
which could be self-assembled on gold substrate and form nanometer strips on gold film with single crystal orientation. In this paper
a serials of brancded thiols were synthesised by using ether reaction. In the experiment
some different reaction route was carried out
the reaction efficiency was evaluated by HPLC method. A optimized reaction route was obtained. Furthermore
through computer simulation
the anchoring energy of this special film surface with nanometer strip was as large as that of conventional rubbing PI film.
