On reoxidation ingress of anion into this compact layer would be hard. We have already shown that the carboxylic acid groups are delocalised into the trimer redox system [11]. We would therefore expect that field assisted dissociation of the carboxylic acid moieties would occur...

As comes from the above discussion, both ro(F) and Q(F) must be taken into account for the general case of the field-assisted dissociation of excited states. Then, t](F) can be... 

Popovic et al. (1987) studied photogeneration of N,N-bis(methyl)perylene-3,4,9,10-tetracarboxyldiimide by field modulation of the time-resolved fluorescence. The results show that the field increases the rate of decay of fluorescence but leaves the initial intensity unchanged. The results were described by a process which occurs by the field-assisted dissociation of the first-excited singlet state. The absence of quenching of the initial fluorescence (amplitude quenching) was interpreted as evidence that the photogeneration process cannot be described by Onsager theories.
