Mayamwidwe ndi mawonekedwe a fluorescence a fast violet-B (FVB) ndi benzanilide (BA) adawunikidwa mu zosungunulira zosiyanasiyana, pH ndi beta-cyclodextrin.Kuphatikizika kwa FVB yokhala ndi beta-CD kumafufuzidwa ndi UV-yowoneka, fluorimetry, AM 1, FTIR ndi SEM.Kuchuluka kwa mayamwidwe a FVB (m'malo mwa anilino) kumakhala kofiira kuposa BA, koma kulowetsedwa kwa benzoyl sikunasinthe mawonekedwe a BA.Poyerekeza ndi BA, kuchuluka kwa emission kwa FVB nthawi zambiri kumakhala buluu mu cyclohexane ndi zosungunulira za aprotic, koma zosungunulira zofiira zimasunthika muzosungunulira za protic komanso kutalika kwa mawonekedwe a FVB ndi chifukwa cha kusamutsa kwa intramolecular charge (TICT).Mu BA, umuna wabwinobwino umachokera kumalo osangalatsidwa kwanuko komanso kutalika kwa mawonekedwe atali chifukwa cha kusamutsidwa kwa proton mu intramolecular/aprotic solvents komanso mu zosungunulira za protic chifukwa cha TICT state.Kafukufuku wa beta-CD akuwonetsa kuti, FVB imapanga 1:2 zovuta kuchokera ku 1: 1 zovuta komanso BA imapanga 1:2 zovuta ndi beta-CD.
