Calix[4]pyrrole can form host-guest complexes with certain thallium salts, for example, TlF, not only in the gas phase but also in solution and in the solid state. The complexation of TlF by calix[4]pyrrole was found to promote self-assembly and the formation of well-defined and highly ordered fibrous supramolecular morphologies, as revealed by polarizing microscopy and scanning electron microscopy. The findings reported here serve to broaden the scope of cationic substrates that may be complexed as ion pairs by calix[4]pyrrole receptors while setting the stage for the development of new hosts for thallium(I) salts.
冠醚[4]吡咯可以与某些铊盐（例如 TlF）形成主客体配合物，不仅在气相中，而且在溶液中和固态中也是如此。通过偏光显微镜和扫描电子显微镜发现，冠醚[4]吡咯与 TlF 的络合作用促进了自组装以及高度有序的纤维超分子形态的形成。这里报道的发现拓宽了可以与冠醚[4]吡咯受体形成离子对的阳离子底物的范围，同时也为开发铊（I）盐的新型主体奠定了基础。
