Complexation-induced nanoarchitectonics of sulfonate cailx[4]resorcinol substituted at the upper rim by N-methyl-d-glucamine fragments: Morphological transition and in vitro anticancer activity

Dual Brønsted acidic-basic function immobilized on the 3D mesoporous polycalix [4]resorcinarene: As a highly recyclable catalyst for the synthesis of spiro acenaphthylene/indene heterocycles

“…Calix [4]resorcinarene (C4RA) is one of the derivatives of C4A, made up of four resorcinol units connected by methylene bridges [ 56 , 57 ]. The substituent groups at the methylene bridges determine the conformers of C4RA, resulting in five stable isomers [ 56 , [58] , [59] , [60] , [61] , [62] ]. Modifying C4RA through various functional groups onto the eight hydroxyphenyl groups and aromatic rings provides a versatile platform for their multi-purpose use.…”
