Abstract : Cyclodextrin inclusion complexes were formed from p-nitroanilines and aniline analogs as well as from selected bimanes. Only in very few instances did complexation with cyclodextrins increase the second harmonic generation when compared to the parent compound (aniline/analog or bimane). Solid state UV reflectance spectroscopy was found to be a viable method for differentiating between solid cyclodextrin-guest inclusion complexes and cyclodextrin-guest physical admixtures. Isobestic points could be determined by solution UV absorption spectroscopy for a number of p-nitroaniline/analog aqueous solutions containing cyclodextrins. The TLC characteristics of p-nitroanilines and their analogs were greatly affected by the presence of cyclodextrins in the mobile phase. Stability constants were calculated from the TLC data. jg p.1
