We have developed a new method to construct nanospace around a single
molecule using dendrimer architectures on surfaces so that the individual
molecules can function without intervention from the neighbors, like
electrical cross-talk, mechanical contact and so on.
Our new method is as follows: First, a self-assembled monolayer of
dendrimers having a functional molecule with a sticky group on the
surface is formed on Au or Si surface. The functional molecule is
focally-substituted with the dendrons through bonding labile to external
stimuli such as a base, light, etc. Second, the dendron spacers are
removed by external stimuli so that a single-molecule-array with a
lattice spacing dependent on the size of the dendron is left on the
surface.
Taking advantage of this new method, we are now developing complicated
single-molecular devices.
