29. We attempted to introduce the thiol group at the initial stage of our research. However, it was difficult to synthesize the counterpart of 3 with the thiol group. The reaction yielded a cyclic compound rather than a linear compound because of the intramolecular reaction that occurred due to the high reactivity of the primary alkyl bromide and thiol groups.
30. A question for the stability of the chemisorbed polysilane molecules is still open. We should prepare not only 3 but also the linkers with one or two sulfide groups for comparison. The washing conditions, especially the time and temperature, must be considered as well for further discussions of the stability.
