Under certain conditions, highly specific fluorescence spectra, showing molecular vibrations as in infrared spectroscopy, can be obtained for the analysis of compounds separated in TLC and microbore LC. Two techniques, both employing low-temperature solid samples, are available: Shpol'skii spectroscopy and Fluorescence Line-Narrowing (FLN) spectroscopy. The former utilizes n-alkane solvents, which form regular, crystalline solids; the latter is based on selective laser excitation. Both techniques can be applied for detection in TLC. FLN is more feasible, since the Shpol'skii method requires spraying of the TLC plate, which leads to significant spreading of the spots. FLN can also be used for offline detection in micro-LC after immobilization of the column effluent on a TLC plate. In addition, some exploratory experiments on the applicability of FLN for on-column detection in LC are presented.

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.
