Intramolecular charge resonance interaction in meso-2,4-bis(4-(4-nitrostyryl)pyridinium)pentane ditetraphenylborates upon steady photolysis in solution
A new omega,omega'- type bichromophoric model compound, meso-2,4-bis (4-(4-nitrostyryl)pyridinium)pentane (meso-B4SPC5(2+)) ditetraphenylborates, has been prepared. A conformational analysis of meso-B4SPC5(2+) was performed by using H-1 NMR spectroscopy. Its charge resonance bands were also studied by absorption spectroscopy upon steady photolysis at room temperature.
