The photoinjection efficiency of holes into anthracene by irradiated aqueous I3- electrodes is decreased by the application of an external magnetic field of up to 100 kG. The effect is attributed to the magnetic field enhanced dissociation of electronically excited I2 (I2*) in solution. The I2* is proposed as a photodissociation product of excited I3-. Atomic iodine does not seem to play a major role in the photoinjection process. The action spectrum is given and a kinetic scheme is proposed. Preliminary results on tetracene, perylene, and dinitronaphthalene show great differences from anthracene.
