Coordination of Alkaline Earth Metal Ions in the Inverted Cucurbit[7]uril Supramolecular Assemblies Formed in the Presence of [ZnCl4]2− and [CdCl4]2−

“…The Q [7] drug-delivery system has attracted extensive attention owing to its water solubility and suitable portal and cavity sizes. [3][4][5][6][7][8][9][10][11][12] For example, Wheate [3] claimed that partial or full encapsulation within Q [7] and its homologuesc ould provide steric hindrance to platinum(II)-a nd platinum(IV)-based complexes, which are considered potential anticancer drugs that are degraded by peptides and proteins,a nd the use of differentiallys ized Q[n]s would allow tuningo fd rug-release rates, cytotoxicity,a nd toxicity.N au [5] demonstrated aQ [7]-Thioflavin T-M + alkali system that responds to the addition of metal ions, and it shows promise for drug-delivery applications.D ay [1] suggested that Q[n]h as the potential to contribute to the resolution of somed rug-delivery difficulties,i ncluding bioavailability and biological and chemical stability,a nd it may also cause improvements in efficacy and efficiency and limit toxicity and side effects. [10] Isaacs and Kim [13] first reported an isomer of Q [7],t he inverted cucurbit [7]uril (iQ [7];F igure 1a,b), andi n as ubsequenti nternational patent for inverted cucurbit[n]uril compounds (i x Q[n]s, x = 1; n = 6, 7), they claimed that i x Q[n]s selectively recognize guest molecules by the shape and dimen-sions of their cavities.…”

“…Recently,w ef ound that iQ [6] could be easily isolated from Q [6] by column chromatography by using aD owex( H + form) resin; [17] the subtle differences in the outer-surface interactions of Q [6] and iQ [6] result in as ignificant difference in the chromatographic behavior of the two Q [6]s. Therefore, iQ [7] should present similarc hromatographic behavior.…”

Synthesis, Photophysical, and Morphological Properties of Azomethine‐Persylilated α‐Cyclodextrin Main‐Chain Polyrotaxane

“…[11][12][13][14][15][16][17][18][19][20] The encapsulation into macrocyclic cavities, i.e., native cyclodextrins (CDs) of PAMs present noticeable advantages for optoelectronic applications, compared to those observed on nonrotaxane counterparts, due to easier processability and adhesivity on the substrates of solid fi lms, as well as the improvements of morphological characteristics. [ 16,17,19,21,22 ] The use of permodifi ed CDs derivatives, which exhibit higher solubility in nonpolar organic solvents and lower propensity to aggregate formations [ 23,24 ] has been employed as an alternative supramolecular approach for the synthesis of polyrotaxanes with conjugated polymers. [25][26][27][28][29][30] Recently, permethylated αCD has been shown to produce PAMs main-chain polyrotaxanes with better solubility in common organic solvents and easier processability with respect to the nonrotaxane ones.…”
