The ultrafast dynamics and nonlinear optical properties of tribranched styryl derivatives based on 1,3,5-triazine

Article Abstract:

The ultrafast response and the nonlinear optical properties of three molecules with donor-acceptor structure are studied using the femtosecond laser spectroscopic techniques. The results suggest that by changing the solvent from chloroform to dimethyl sulfoxide, the transient dynamics was found changed significantly and the decay time of photoluminescence (PL) emission decreased dramatically.

Proton transfer in nanoconfined polar solvents. 1. Free energies and solute position

Article Abstract:

The reaction free energy curves for a model phenol-amine proton-transfer system in a confined chloroform solvent are calculated by Monte Carlo simulations. The results indicate that the reaction complex position can be an important component of the reaction coordinate for proton-transfer reactions in nanoconfined solvents.

Synthesis and optical properties of silver nanowire arrays embedded in anodic alumina membrane

Article Abstract:

Transparent Ag nanowire arrays embedded in anodic alumina membranes are prepared by a template-based approach combined with ac electrodeposition and subsequent etching of substrate. The optical response of the structure could be attributed to surface plasmon resonance of Ag nanowires.
