Host–guest interaction of l-tyrosine with β-cyclodextrin

Spectrofluorometric Study of the Inclusion Complexation of Fluorescent Whitening Agents and <i>β</i>-Cyclodextrins

“…Since cyclodextrins have a hydrophobic cavity of different dimensions depending on the number of glucose units forming the ring (α-CD: 5.2Å, β-CD: 6.6Å and γ-CD: 8.4Å), they can bind with various guest molecules forming supramolecular host-guest complexes [1] [2] [3] [4].…”

Fluorescence Studies of the Hydrogen Bonding of Excited‐State Molecules within Supramolecular Host–Guest Inclusion Complexes

“…This host-guest hydrogen bonding, together with the lower cavity polarity, results in a large enhancement of the observed TICT emission. Effects of direct hydrogen bonding interactions between an included guest and the CD hydroxyls on guest TICT or ICT emission have also been reported for Nile Red (g-CD) [73,74], 2-aminodiphenylsulphone (b-CD) [75], L-tyrosine (b-CD) [76] and 2-(4-(dimethylamino) styryl)-1-methylpyridinium iodide (g-CD) [77].…”

“…There have been a number of reports on the effects of hydrogen bonding of TICT states of guests within CD cavities [65][66][67][68][69][70][71][72][73][74][75][76][77]. Nag and Bhattacharyya studied the TICT emission of dimethylaminobenzonitrile (DMABN) in a-CD [65].…”

Supramolecular Interactions of Nonsteroidal Anti‐inflammatory Drug in Nanochannels of Molecular Containers: A Spectroscopic, Thermogravimetric and Microscopic Investigation

“…A stoichiometric amount of IMC was then dissolved in spectroscopic grade methanol (20 mL) in a 50 mL beaker. IMC solution was added dropwise into the CD solution as described previously, [49] whereupon a white precipitate formed. The turbid solution was then continuously stirred for 48 h at RT, then the solution was kept in a refrigerator for 48 h. The precipitated solid was filtered through Whatman filter paper and washed with Millipore water.…”
