The photo-physical properties of the 4-methoxy and 4-acetamide 1,8-naphthalimide N-substituted with the ethyldialkylamino groups, show a photo-induced charge transfer effect (PCT). The addition of protons to the solution blocked this effect and the molecules have an intense laser emission in polar solvents such as acetonitrile and ethylene glycol. We present here the photo-physical properties of the...
In this work, a study on the photochemical and sonochemical behaviour of norharmane in halomethane media (dichloromethane, chloroform, carbon tetrachloride and dibromomethane) is presented. When solutions of norharmane in these media are irradiated with UV light or sonicated with ultrasound at 20 or 50 kHz, the cationic species of norharmane appears in solution. In order to explain the formation of...
