Intramolecular charge transfer in 1:1 Cu(II)/pyrenylcyclam dendrimer complexes

Article Abstract:

Two newly synthesized pyrenylcyclam dendrons have displayed unique emissive blue shifts centered at 450 nm upon adding copper triflate, which are attributed to intramolecular excimer emission. Metal complexation and intramolecular photoinduced electron transfer within the dendritic 1:1 cyclam/metal complex have played vital roles in the photophysical properties in metal/dendrimer complexes.

Effect of temperature and pressure in the photocatalytic oxidation of n-octanol on partially desilanized hydrophobic TiO2 suspended in aerated supercritical CO2

Article Abstract:

The photocatalyzed decomposition of n-octanol as a model organic compound by TiO2 oxidative photocatalysis in aerated supercritical CO2 (scCO2) is studied. It was found that hydrophobic TiO2, Degussa T805, is suitable as a photocatalyst in scCO2.
