Photophysical and acid-base properties of para-substituted N,N-dimethylanilines

- pKa values in the ground and excited state were determined for para-substituted N,N-dimethylanilines.
- Proton dissociation constants changes are explained in terms of the electronaccepting ability of the acceptor moiety.
- Protonated aniline derivatives in aqueous solutions undergo very fast excited-state proton dissociation.
