I-absorption and fluorescence spectra of fast violet-B (FVB) kunye ne-benzanilide (BA) ihlalutywe kwii-solvents ezahlukeneyo, i-pH kunye ne-beta-cyclodextrin.I-complex edibeneyo ye-FVB ene-beta-CD iphandwa yi-UV-ebonakalayo, i-fluorimetry, i-AM 1, i-FTIR kunye ne-SEM.Ubuninzi bokufunxa be-FVB (i-anilino endaweni) butshintshiwe bubomvu kunobo be-BA, kodwa ukutshintshwa kwe-benzoyl akuzange kutshintshe ubume bemeko ephantsi ye-BA.Xa kuthelekiswa ne-BA, ubukhulu bokukhutshwa kwe-FVB ubukhulu becala obuluhlaza butshintshiwe kwi-cyclohexane kunye nezinyibilikisi ze-aprotic, kodwa ubomvu butshintshile kwi-protic solvents kunye nobude be-wavelength maxima kwi-FVB kungenxa yokudluliselwa kwentlawulo ye-intramolecular (TICT).Kwi-BA, ukukhutshwa okuqhelekileyo kuphuma kwimeko echulumancisayo yasekhaya kunye nebhendi yobude bexesha elide ngenxa yokudluliselwa kweproton ye-intramolecular kwizinyibilikisi ezingezo-polar/aprotic kunye nakwizinyibilikisi zeprotic kungenxa yemeko ye-TICT.Uphononongo lwe-beta-CD lubonisa ukuba, i-FVB yenza 1:2 entsonkothileyo ukusuka ku-1:1 entsonkothileyo kunye neefom ze-BA eziyi-1:2 ezine-beta-CD.
