Tetra-azobenzene extended calix[4]pyrroles: influence of photo-isomerization on chloride binding and its transport through liposomal membranes

“…Other tetra-azobenzene extended C [4]P have been previously reported, but their photoisomerization behaviors and binding properties were not described. 17,18 Very recently, Wezenberg and co-workers reported the synthesis of a strapped calix [4]pyrrole receptor with a stiff-stilbene unit incorporated in the strap. 19 The switching of the stilbene unit between its Z and E forms significantly reduced the size of the macrocyclic anion binding pocket delimited by the strap.…”

Efficacious Removal of Flonicamid Insecticide from Water by GO@functionalized Calix[4]pyrrole: Synergistic Effect in Adsorption

“…Calixpyrrole represents a family of supramolecular compounds which are analogues to calixarene. [23] When compared to the chemistry of "traditional" calixarenes, calixpyrroles are particularly attractive compounds due to their unique properties. [24] Numerous receptors can be generated using calix [4]pyrroles due to their huge potential for functionalization.…”

Synthesis and Binding Studies of a Tetra‐α Aryl‐Extended Photoresponsive Calix[4]pyrrole Receptor Bearing meso‐Alkyl Substituents

“…Tetraazobenzene‐extended calix[4]pyrroles bearing meso ‐methyl substituents were previously reported in literature, however, their molecular recognition and photo‐isomerization properties were not explored , . Herein, we describe an alternative synthetic route for the preparation of tetraazobenzene‐extended calix[4]pyrroles.…”

“…[27,28] Tetraazobenzene-extended calix [4]pyrroles bearing mesomethyl substituents were previously reported in literature, however, their molecular recognition and photo-isomerization properties were not explored. [29,30] Herein, we describe an alternative synthetic route for the preparation of tetraazobenzene-extended calix [4]pyrroles. The prepared receptor was isolated as pure tetra-α configurational isomer bearing meso-alkyl substituents functionalized with a terminal ethyl ester.…”
