Photophysics of reduced silicon tetraphenylporphyrin

Article Abstract:

Static absorption and fluorescence spectroscopy and ultrafast transient absorption measurements are used to investigate the contrasting photophysical properties of two silicon (IV) tetraphenylporphyrins (Si(Tpp)[(py).sub.2] and Si(Tpp)[Cl.sub.2]). The results have shown that the connection between structural distortions and the presence of low-energy excited states have given rise to ultrafast nonradiative deactivation of the photoexcited molecule to the ground electronic state.

Multinuclear magnetic resonance spectroscopy studies of the structuration of the tunnels of sepiolite in the presence of intracrystalline pyridine molecules

Article Abstract:

A study on the structration of the tunnels of sepiolite in the presence of intracryatalline pyridine molecules using multinuclear magnetic resonance was conducted. The results revealed that the pyridine molecule in the inorganic-organic nanohybrid material is directly bound to magnesium cations exposed in the tunnels of sepiolite.
