Charge transfer control by substituents: Donor pyrroles and fluoro-anilines
Derivatives of N-phenyl pyrrole with a para-donor substituent on the acceptor benzene ring are compared. It is shown that by a suitable increase of the donor strength of the pyrrolo group, CT fluorescence can be achieved even for donor-donor substituted benzenes. On the other hand, introducing fluor...

| Summary: | Derivatives of N-phenyl pyrrole with a para-donor substituent on the acceptor benzene ring are
compared. It is shown that by a suitable increase of the donor strength of the pyrrolo group, CT fluorescence
can be achieved even for donor-donor substituted benzenes. On the other hand, introducing fluoro
substituents into the acceptor moiety strongly enhances the CT formation tendency, and several new compounds
with CT fluorescence even in alkane solvents are presented. |
