Calixarenes and Their Biomimetic Applications [PDF]
Bioinorganic Chemistry and Applications, 2004 The synthetic models for the structures, spectroscopic properties and catalytic activities of metalloprotein active sites have been reviewed. Calixarenes were used as new biomimetic catalysts because of their advantage of providing preorganiiation of the catalytic group, which can bind the substrate dynamically that results in fast turnover and fast ...

The synthesis and medicinal applications of pyrogallol4arenes [PDF]
, 2006 To date almost all pyrogallol[4]arenes reported in the literature have been prepared from alkyl aldehydes. We were interested in preparing more pyrogallol[4]arenes from commercially available benzaldehydes.

Chiral Phosphinoferrocenyl‐Calixarenes [PDF]
European Journal of Organic Chemistry, 2016 The Mitsunobu alkylation of 4‐tert‐butylcalix[4]arene with (S)‐(2‐diphenylthiophosphinoferrocenyl)methanol followed by desulfuration of the thiophosphine unit using tris(dimethylamino)phosphine afforded enantiomerically pure calixarene mono‐ and di(ferrocenylphosphine) ligands in high yields.

Reactivity of carbonyl and phosphoryl groups at calixarenes [PDF]
, 2013 Examples of reactivity of carbonyl and phosphoryl compounds controlled by calixarenes are illustrated in this review article. The molecular framework of calixarenes has been widely used as a versatile molecular platform for the dynamic arrangement of one

Chemistry – A European Journal, EarlyView.Seven novel supramolecular photosensitizers based on benzo[c][1,2,5]thiadiazole (BTZ) tethered to calix[4]arene (C[4]) scaffolds are reported with facile, scalable, and selective syntheses. Their abilities to produce singlet oxygen have been tested through the photo‐oxidation of α‐terpinene.

Synthesis and Host–Guest Properties of Acyclic Pillar[n]naphthalenes
Frontiers in Chemistry, 2019 Here we report a new class of synthetic receptors, acyclic pillar[n]naphthalene (n = 2–4, Dimer, Trimer, and Tetramer) oligomers, which are made up of 2,3-diethoxynaphthalene units linked by methylene bridges at the 1- and 4-positions.

Gold nanoparticles: calixarene complexation in a mixed calixarene–alkanethiol monolayer
RSC Advances, 2014 This paper describes a detailed study on the complexation of pyridinium derivatives with calixarenes bound to gold nanoparticles (AuNPs). The studied calixarene derivatives are mixed with alkanethiols to form mixed monolayers on AuNP surfaces. The key findings are: (i) even a small amount (less than 11 mol%) of calixarenes can retain their complexation

Modulation of Epigenetic Control by Advanced Molecular Tweezers
Chemistry – A European Journal, EarlyView.Tailored dimeric molecular tweezers recognize the DNA‐binding part of Histone H4 and interrupt the essential histone‐DNA interaction. ABSTRACT This work addresses the question if supramolecular systems can be tailored to interfere with posttranslational modifications (PTM) and epigenetics.
