been shown to exhibit high affinity to anions, a cyclicnitrone conjugate of calix[4]pyrrole (CalixMPO) was designed, synthesized, and characterized. Computationalstudies at the PCM/B3LYP/6-31+G(d,p)//B3LYP/6-31G(d) level suggest a pendant-type linkage between the calix[4]pyrrole and the nitrone to be the most efficient design for spin trapping of O2(•-), giving exoergic reaction enthalpies (ΔH(298K
