The photophysics of nitrocarbazoles studied by using spectroscopic, photoacoustic and luminescence techniques
The photophysical behaviour of 1-nitrocarbazol and 3-nitrocarbazol in different organic solvents has been studied by using spectroscopic, luminescence and photoacoustic techniques. Absorption spectra and triplet state transient spectra were recorded and formation quantum yields and lifetimes determi...
