The 351.1 nm photoelectron spectrum of imidazolide anion has been measured. The electron affinity (EA) of the imidazolyl radical is determined to be 2.613 +/- 0.006 eV. Vibrational frequencies of 955 +/- 15 and 1365 +/- 20 cm(-1) are observed in the spectrum of the (2)B1 ground state of the imidazolyl radical. The main features in the spectrum are well-reproduced by Franck-Condon simulation bas...

Control of function in self-assembled molecular structures is a major challenge in supramolecular chemistry. [ 1–4 ] Ion channels, for instance, are pore-forming nanostructures typically comprising multiple molecular subunits assembled via noncovalent interactions. [ 5 ] These pores function by facilitating a fl ux of ions across the hydrophobic barrier of a lipid bilayer. For over a decade, ma...

A new deep acceptor state is identified by density functional theory calculations, and physically activated by an Au ion implantation technique to overcome the high energy barriers. And an acceptor-compensated charge transport mechanism that controls the chemical sensing performance of Au-implanted SnO2 nanowires is established. Subsequently, an equation of electrical resistance is set up as a ...
