calixarenes |
Originally macrocyclic compounds capable of assuming a basket (or "calix") shaped conformation. They are formed from p-hydrocarbyl phenols and formaldehyde. The term now applies to a variety of derivatives by substitution of the hydrocarbon cyclo{oligo[(1,3-phenylene) methylene]}. C. D. Gutsche, Calixarenes, The Royal Society of Chemistry, 1989.
