Nitrogen-containing oxacalixarene and calixarene derivatives, polymers including groups related to such derivatives, polymers including groups related to such derivatives, and use of such compounds

摘要

The application described a nitrogen-containing oxacalixarene or calixarene derivative of formula I: whereinm′ + m˝ = 0-8n = 0-8m¹ ≧ 1/₂ (m′ + m˝)3 ≦ m′ + m˝ + n ≦ 8if n = 0, m′ + m˝ ≧ 4R³ is H, halogen, or hydrocarbyl, aryl, hydrocarbylaryl or a substituted derivative thereof and R³ may be the same or different on each aryl group;R¹ and R¹⁵ which may be the same or different are H or hydrocarbyl, aryl, hydrocarbylaryl or a substituted derivative thereof;R² is selected from:R⁴ which is H, or hydrocarbyl, aryl, hydrocarbylaryl or a substituted derivative thereof, wherein R⁵ and R⁶ which may be the same or different are H, or hydrocarbyl, aryl, hydrocarbylaryl, or a substituted derivative thereof,-OR¹, wherein R¹ is as defined aboveand R¹⁷ 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 R² is R¹⁷.;The derivatives may be polymer-bound. Use of the derivatives for sequestration of metals is also described.
