In this work, we study the induced optical activity (OA) of spin-coated molecular films made of a pristine optically inactive laser dye (Rhodamine 110) in the visible range. The OA is brought about by a “transparent” chiral modifier (1,1′-Bi-2-

Water-soluble ligand protected optically active silver nanostructures were synthesised in a one-step reduction and capping process mediated by thiol-containing biomolecules. The synthesis was performed successfully with d- and l-cysteine and l-glutat

ConspectusMass-selected Ptn+ ion deposition in ultrahigh vacuum (UHV) was used to prepare a series of size-selected electrodes with Ptn (n ≤ 14) clusters supported on either glassy carbon (GC) or indium tin oxide (ITO). After characterization of th

We have studied the circular dichroism (CD), in the ultraviolet and visible regions, of the transparent, chiral molecule 1,1’-Bi-2-naphtol (BINOL) in 1.5 μm thick films. The initial transparent film shows an additional negative cotton effect in th

The one-electron-reduced (OER) species of rhenium-based catalysts in the homogeneous photocatalytic reduction of CO2 represents the starting point of light-induced deactivation processes, which lead to low catalyst activity and productivity. Herein,

In this work, we present an experimental setup for the in situ and ex situ study of the optical activity of samples, which can be prepared under ultra-high vacuum (UHV) conditions by second-harmonic generation circular dichroism (SHG-CD) over a broad

The extinction spectra of size-selected, supported Ag20 and Ag55 clusters have been measured with surface cavity ring-down (s-CRD) spectroscopy under ultrahigh vacuum (UHV) conditions. A single plasmonic resonance around 3.2 eV is observed. The react
