Among other things, the calixarene may be bonded to a crown ether for ion detection or bonded to a area for the recognition of explosives by hydrogen bonding to nitro groups.Type: ApplicationFiled: September 14, 2005Publication date: August 28, 2008Applicants: UT-BATTELLE, LLC, UNIVERSITY OF TENNESSEE RESEARCH FOUNDATIONInventors: Lal A.
