Calix[4]pyrrole 1 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 1 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.

hall盐：杯[4]吡咯的新伙伴

Calix [4]吡咯1可以与某些th盐（例如TlF）在气相中，也可以在溶液和固态中形成主体-客体复合物。通过偏光显微镜和扫描电子显微镜发现，杯芳烃[4]吡咯1与TIF的络合促进了自组装并形成了明确且高度有序的纤维超分子形态。此处报道的发现有助于拓宽阳离子底物的范围，这些阳离子底物可能与杯[4]吡咯受体作为离子对复合，同时为开发新的hosts（I）盐宿主奠定了基础。
