STUDY OF ELECTRON TRANSFER REACTION IN RHODAMINE 6G - AMINE SYSTEMS

Electron transfer (ET) reactions between excited Rhodamine 6G (Rh6G) dye and different amines, n-butyl amine (BTA) and triethyl amine (TEA) donors, have been investigated in the solvents DMF and DMSO using steady – state (SS) and time-resolved (TR) fluorescence quenching measurements. No ground state complex has been indicated in these systems. SS and TR measurements give similar quenching constants for each of the Rh6G – amine pairs, suggesting dynamic nature of interaction in these systems. 1H NMR spectra of Rh6G without and with BTA and TEA have
