Abstract
Chemotherapy is one of the most employed strategies in clinical treatment of cancer. However, reducing medication adverse effects and improving the biological activity remains a significant issue for chemotherapy. We developed a pH and Ca2+-responsive pillar[5]arene-based supramolecular nanodrug delivery system (NDDS) WP5⊃EV@DOX to address the aforementioned challenges. The formation of this NDDS began with the spontaneous formation of supramolecular nanodrug carrier WP5⊃EV in water from PEG-modified pillar[5]arene and the bipyridilium salt derivative EV through simple host-guest interaction. Then the antitumor drug doxorubicin DOX was efficiently loaded with a high encapsulation rate of 84.6 %. Cytotoxicity results indicated that the constructed nanoplatform not only reduced DOX toxicity and side effects on normal cell (293T), but also significantly enhanced the antitumor activity on cancer cell (HepG2). Moreover, in vivo experiments showed that WP5⊃EV@DOX had a longer half-life and higher bioavailability in the blood of mice compared to the nake drug DOX, with increases to 212 % and 179 %, respectively. Therefore, WP5⊃EV@DOX has great potential in tumor therapy and provides a new idea for host-guest drug delivery system.

Abstract
With the increasing issues of environmental degradation and health problem, the selective detection of toxic ions has attracted considerable attention from researchers. Chemical fluorescent sensors with the advantages of facile operation, high sensitivity, rapid response, and easy visualization are emerging as powerful detection tools towards ions. However, the selective recognition of ions is always hindered by the presence of other interfering substances. Herein, we show that supramolecular host-guest interaction based on a pillar[5]arene provides a new opportunity to regulate the ionic recognition properties of guest molecules. A pillar[5]arene-based host-guest complex HG was constructed through the host-guest interaction between ammonium functionalized pillar[5]arene (HAP5) and 2,2'-bibenzimidazole (G). The host-gust complex HG can realize the successive, highly selective, and sensitive detection of specific ions. It was found that only in the presence of HAP5, the sensitivity towards cations was evidently enhanced, and selective successive recognition for I- and HSO4- was achieved. Those results indicate that the introduction of HAP5 can effectively improve the ion recognition performance of 2,2'-bibenzimidazole, so it is a feasible strategy using supramolecular host-guest interaction to regulate the ionic recognition properties of guest molecules.
