Abstract
The photochemical properties of the di-Schiff base 2 have been investi gated. The first reaction step of 2 in 2-propanol or in cyclohexane is an intramolecular photoreductive coupling affording the diazocine mes o-4. Subsequent photoreactions of meso-4 in 2-propanol are studied. In concentrated solutions of phenanthridine in cyclohexane a photodimeri zation takes place during which two CH bonds are broken and two NH bon ds are formed. The photodimer reconverts with high quantum yield quant itatively to the monomer.
