    摘要： The application describes nitrogen-containing an oxacalixarene or calixarene derivative of formula I: ##STR1## wherein m'+m"=0-8n=0-8m'.gtoreq.1/2(m'+M")3.ltoreq.m'+m"+n.ltoreq.8if n=0, m'+m".gtoreq.4R.sup.3 is H, halogen, or hydrocarbyl, aryl, hydrocarbylaryl or a substituted derivative thereof and R.sup.3 may be the same or different on each aryl group;R.sup.1 and R.sup.15 which may be the same or different are H or hydrocarbyl, aryl, hydrocarbylaryl or a substituted derivative thereof;R.sup.2 is selected from:R.sup.4 which is H, or hydrocarbyl, aryl, hydrocarbylaryl or a substituted derivative thereof, ##STR2## wherein R.sup.5 and R.sup.6 which may be the same or different are H, or hydrocarbyl, aryl, hydrocarbylaryl, or a substituted derivative thereof,-OR.sup.1, wherein R.sup.1 is as defined aboveand R.sup.17 which is a residue of a hydrocarbyl, aryl, or hydrocarbylaryl group or of a substituted derivative thereof providing a bond to another oxacalixarene or calixarene derivative of formula I wherein R.sup.2 is R.sup.17.The derivatives may be polymer-bound. Use of the derivatives for sequestration of metals is also described.
