Chemistry of Cavitands

Functionalization reactions of calixarenes

“…This contribution is a continuation of our previous works concerning calixarenes, 74 their complexes with metal ions, 75,76 covalently and noncovalently bound calixarene assemblies, 77 and cavitands, 78 forming dimeric, 79 as well as trimeric and hexameric, 80 capsules. Since the amount of reports dealing with calixarenes is enormous, only selected examples are described in this review.…”

Inclusion Complexes Containing Quaternary Azaaromatic Moieties

“…Many papers describing interlocked species 1-5 as well as inclusion complexes of cavitands [6][7][8] and of calixarene-based capsules [9][10][11] appear. Many papers describing interlocked species 1-5 as well as inclusion complexes of cavitands [6][7][8] and of calixarene-based capsules [9][10][11] appear.…”

“…Many papers describing interlocked species 1-5 as well as inclusion complexes of cavitands [6][7][8] and of calixarene-based capsules [9][10][11] appear. 8,11,26 Quaternary azaaromatics are a topic of a number of reports; due to their interesting properties and application possibilities 17 inclusion complexes containing these species are important, for example in the construction of molecular machines and switches. [12][13][14] The present review is a continuation of our former papers on quaternary azaaromatics, 15-19 supramolecular spieces of a quaternary azaaromatic character, [20][21][22] as well as on cyclodextrins [23][24][25] and calixarenes.…”

“…When aqueous solution of dequalinium chloride (8), which is an antibacterial drug is treated with β-CD, a strong increase of fluorescence intensity occurs due to the formation of 1:1 host-guest complex; this behavior enables the determination of 8 in bulk aqueous solutions in the presence of β-CD by flow injection spectrofluorometric method. It should be noted that it is the order of increasing basicity of the medium.…”
