摘要：

Trimethylammonium-derived alkynylplatinum(II) terpyridine molecular tweezers have been designed and synthesized in this manuscript. They show moderate binding affinity towards the complementary organoplatinum guest in polar media, such as DMSO, methanol, and water, even though the guest itself is sparingly soluble in the latter two solvents. Responsive guest encapsulation/release from the cavity of molecular tweezers can be achieved by successive addition and removal of trifluoroacetic acid, accompanying with remarkable switching of the photophysical signals, which would benefit for the fabrication of intelligent supramolecular materials with tailored functionalities.
