Meng-Di Gu Yao Lu Mei-Xiang Wang MOE Key Laboratory of Bioorganic Phosphorous Chemistry and Chemical Biology, Department of Chemistry, Tsinghua University, Beijing 100084, China 10.3762/bjoc.15.193 Abstract Functionalized O6-corona[3]arene[3]tetrazines were synthesized efficiently and
adopt the conformation in which three phthalimide units are cis,trans-orientated. Acting as electron-deficient macrocyclic hosts, the synthesized O6-corona[3]arene[3]tetrazines self-regulated conformational structures to complex anions in the gas phase and in the solid state owing to the anion–π
noncovalent interactions between anions and the tetrazine rings.

Synthetic macrocycles [1][2] are always attractive and important because they are unique
