ABSTRACT Cucurbit[10]uril (CB[10]) is found to form stable host-guest complexes with tetracationic cyclophanes in H2O and DMSO. Upon encapsulation in CB[10], the affinity of cyclophanes towards anions is weakened, due to electronegative carbonyl oxygens on CB[10] providing charge repulsion environment, and encapsulation fixing the conformation of cyclophanes. Interestingly, these complexes show positively

Adsorption of calixarene-based supramphiphiles at the solid–liquid interface monitored by QCM-D Supramol. Chem. (IF 3.3) Pub Date : 2022-03-10 Rossella Migliore, Giuseppa Ida Grasso, Paola Milana, Simona Cusmano, Giuseppina D. G. Santonoceta, Carmelo Sgarlata
ABSTRACT Supramolecular amphiphiles are a topic of widespread interest in supramolecular chemistry and the characterisation of their properties at the interfacesis at the basis of industrial and biotechnology applications. This work focuses on the determination of the adsorption features of supramolecular amphiphiles, formed by the host-guest complexation of a p-sulfonatocalix[4]arene with selected

Tiara[6]arenes Supramol. Chem. (IF 3.3) Pub Date : 2022-03-09 Yang Chao, Andrew C.-H. Sue
ABSTRACT Herein we report the successful synthesis and isolation of tiara[6]arene, a constitutional isomer of calix[6]arene consisting of six phenol units linked by para-substituted methylene bridges, from an isomeric mixture of asymmetrically substituted pillar[6]arene intermediates. Similar to its pentameric analogue, tiara[6]arene displays high conformational freedom in solution and rich polymorphism

Sulfated-β-cyclodextrin templated aggregation of a metachromatic dye, Basic Orange 21: A photophysical investigation Supramol. Chem. (IF 3.3) Pub Date : 2022-03-07 Gaurav Singh, Vidya R. Singh, Shrishti P. Pandey, Prabhat K. Singh
ABSTRACT The recently discovered molecular rotor and supravital dye, Basic Orange-21 (BO21), has shown improved differential counting of leukocytes through metachromasia (change in colour), which is believed to be due to the aggregation of chromophores. Thus, investigation on the aggregation behaviour of BO21 holds special importance and may help us to delineate its spectroscopic behaviour. In this
