Time resolved CW-EPR spectroscopy of powdered samples: electron spin polarization of a nitroxyl radical adsorbed on NaY zeolite, generated by the quenching of excited triplet ketones

Article Abstract:

Chemically induced dynamic electron polarization generated in a faujasite zeolite by the interaction between a stable free radical and the triplet state of benzophenone was investigated by time-resolved electron spin resonance spectroscopy. The identification of the polarised nitroxide was confirmed by employing both (super 14)N and (super 15)N 4-oxoTEMPO isotopomers.

Effect of protonation and PAMAM dendrimer size on the complexation and dynamic mobility of 2-naphthol

Article Abstract:

An update of study is presented to use supramolecular recognition to help understand the complexation dynamics of 32-NpOh*@n-SBD. The entry rate constant increases with dendrimer size, that the binding constants derived from the analysis of the dynamic behavior increase with increase pH and that the exit rate constant decreases with an increase in pH.
