Conjugated Molecule

We demonstrate that immobilization of a π-conjugated molecule containing a bipyridine moiety as a hydrogen bond acceptor on Au 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 M -1) in CDCl 3, it was demonstrated that the dendrimer spacer serves as a template to isolate the π-conjugated molecule, and is removable simply with a CH 2 Cl 2 rinsing by surface FTIR spectroscopy.

Linear Solvation

The reaction between phenacyl bromide and 2-mercaptobenzothiazole was studied conductometrically in 17 different protic and aprotic solvents. The second order rate constants determined are found to be highly susceptible to changes in the solvation abilities of the solvents. Correlation of the rate constants with different solvent parameters indicated that the solvation of the reactants and the transition state is due to the electrophilicity, hydrogen bond donor ability, specific polarisability and a non-specific polarity of the solvent. by statistical analysis, a linear solvation energy relationship is derived and the percentage contributions of each type of solvation are estimated.
