摘要：

We demonstrate that immobilization of a pi-conjugated molecule containing a bipyridine moiety as a hydrogen bond acceptor on An using a dendrimer-based template with 3,4-dihydroxybenzene moiety at the core as a hydrogen bond donor. The hydrogen bond interaction was used for the linkage between the conjugated molecule and the template to improve the method to fabricate single-molecule arrays we reported before.(1) Although the binding constant is small (K = 120 20 W) in CDCl3, it was demonstrated that the dendrimer spacer serves as a template to isolate the pi-conjugated molecule, and is removable simply with a CH2Cl2 rinsing by surface FTIR spectroscopy.
