Sidewall functionalization of single-walled carbon nanotubes with nitrile imines. Electron transfer from the substituent to the carbon nanotube

Article Abstract:

A new versatile methodology for functionalization of single walled carbon nanotubes using 1,3-dipolar cycloadition of nitrile imines to the sidewalls of SWNTs is used to synthesize two soluble photoactive single walled carbon nanotubes containing n-pentyl esters at the tips. It was observed that data available including the photochemistry of model compounds, quenching experiments with electron donors and acceptors and influence of acids, are compatible with the occurrence of an electron transfer from the electron rich substituents of the pyrazoline unit to electron acceptor termini including electron poor aryl rings and nanotube walls.

Study of mechanisms of light-induced dissociation of Ru(dcbpy)(CO)2I2 in solution down to 20 fs time resolution

Article Abstract:

Mechanisms of the light induced exchange reaction of (trans-I) Ru(dcbpy)(CO)2I2 in ethanol is studied by transient absorption spectroscopy. Ultraviolet 20 fs excitation pulses centered at 325 nm were used to populate a vibrationally hot excited pi* bipyridyl state of the reactant that quickly relaxes to a dissociative Ru-I* state resulting in the release of one of the carbonyl groups.
