资源简介：
Two new cucurbituril members, one containing two equivalent cavities and the other having an active secondary amine group, were synthesized by condensation of propanediurea (2,4,6,8-tetraazabicyclo[3.3.1]nonane-3,7-dione) with formaldehyde. These two macrocycles exhibit excellent thermal stability, and their structures were confirmed by single-crystal X-ray diffraction, 1H NMR spectroscopy, and high-resolution mass spectrometry.
