Calixarenes and resorcinarenes
Macrocycles with (Almost) Unlimited Possibilities
Calixarenes are cyclic oligomers made up of phenolic units with four, six, or eight phenol units that are joined by methylene bridges. The beakerlike shape of the most stable conformation of the tetramer has led to them being given the name “calixarenes” (calix = chalice). Resorcinol can undergo condensation in a similar manner with a variety of aldehydes to afford cyclic tetramers with the same basic structure (the resorcinarenes). Non modified calixarenes can be modified by chemical reactions and function as “molecular platforms” to which an almost endless range of functional groups can be fixed.
Eburon Organics is a leader in calixarene production and has been producing a broad range of calixarenes and resorcinarenes since 2000. We build further on calixarene technology originally developed at University of Namur by Prof. Krief and continue to provide custom synthesis for calixarene and resorcinarene derivatives.
Highly versatile in its applications
Calixarenes have been subject to extensive research in development of many extracts, transporters, stationary phases, electrode ionophores and optical and electrochemical sensors. separation of neutral organic molecules, stabilizers for organic polymers, pollution control selective complexation of neutral cations, phase transfer agents, accelerators for instant adhesives, ion scavengers for electronic devices, Langmuir-Blodgett film and membranes, catalytic properties.
A long list of applications includes:
Negative resists for high resolution lithography
Recovery of Lanthanides, Caesium, Uranium in nuclear industry
Stabilizer for organic polymers
Separation of neutral organic molecules
Selective complexation of metal cations
Phase transfer agents
Accelerators for instant adhesives
Ion scavengers for electronic devices
Langmuir-Blodgett films and membranes
