Kev nqus thiab fluorescence spectra ntawm ceev violet-B (FVB) thiab benzanilide (BA) tau raug tshuaj xyuas hauv cov kuab tshuaj sib txawv, pH thiab beta-cyclodextrin.Kev suav nrog FVB nrog beta-CD yog tshawb xyuas los ntawm UV-pom, fluorimetry, AM 1, FTIR thiab SEM.Qhov kev nqus siab tshaj plaws ntawm FVB (anilino hloov pauv) yog liab hloov dua li ntawm BA, tab sis kev hloov benzoyl tsis tshua hloov cov qauv hauv av ntawm BA.Piv nrog rau BA, qhov emission maxima ntawm FVB feem ntau xiav hloov pauv hauv cyclohexane thiab aprotic cov kuab tshuaj, tab sis liab hloov hauv cov kuab tshuaj protic thiab qhov ntev wavelength maxima hauv FVB yog vim qhov hloov pauv hloov pauv hloov pauv (TICT).Hauv BA, qhov emissions ib txwm pib los ntawm lub xeev zoo siab hauv zos thiab qhov ntev wavelength band vim kev hloov pauv hauv intramolecular proton hauv cov kuab tshuaj tsis-polar / aprotic thiab hauv cov kuab tshuaj protic nws yog vim TICT xeev.Kev tshawb fawb beta-CD qhia tias, FVB cov ntaub ntawv 1: 2 complex los ntawm 1: 1 complex thiab BA cov ntaub ntawv 1: 2 complex nrog beta-CD.
