A process for the high-yield preparation of p-(R-oxy)calix[9-20]arenes from a mixture of a base, a phenol, a source of formaldehyde and a organic solvent, p-(R-oxy)calix[9-20]arenes obtained from such a process, and uses of such p-(R-oxy)calix[9-20]arenes.
Short segments of zigzag single‐walled carbon nanotubes (SWCNTs) were obtained from a calixarene scaffold by using a completely new, simple and expedited strategy that allowed fine‐tuning of their diameters. This new approach also allows for functionalised short segments of zigzag SWCNTs to be obtained; a prerequisite towards their lengthening. These new SWCNT short segments/calixarene composites show
p-(Benzyloxy)calix[8]arene Synthesis Revisited: p-(Benzyloxy)calix[4]-, p-(Benzyloxy)calix[5]-, p-(Benzyloxy)calix[7]-, and p-(Benzyloxy)bis(homooxa)calix[4]arenes

A detailed investigation of the 4-(benzyloxy)phenol/formal-dehyde reaction shows that along with the previously described p-(benzyloxy)calix[8]arene and p-(benzyloxy)calix-[6]arene, others calixarenes are observed and easily recovered on a preparative scale. All these new calixarenes are opening interesting perspectives for the synthesis of new supramolecular hosts, easily functionalized at the para
