A water-soluble oxatub[4]arene with tri(ethylene oxide) moieties was synthesized. The lower critical solution temperature (LCST) behavior of this macrocyclic receptor was tunable by changing its concentration or by adding an appropriate guest. Most interestingly, the LCST behavior of the host-guest complex showed a response to the presence of the physiological gasotransmitter HS through nitro group reduction.
In this research, we report that the acid/base-switchable molecular shuttle without any photoresponsive group can be controlled photochemically by coupling to the indazole-based photoacid via an intermolecular proton-transfer process. The photocontrolled shuttling of the wheel can be conveniently monitored by following the fluorescent evolution during the photoirradiation.
put in a supine position for NIR-II imaging under an 1100 nm LP filter upon excitation at 808 nm (30 mW cm -2 ), respectively. The fluorescence intensity of lungs was recorded at 0,
The photosensitizer-triggered macrophage-mediated photodynamic immunotherapy is reported. The TPA-DCR NPs induce the ICD of hypoxic tumor by generating type I ROS to polarize macrophage, then promote tumor infiltration of T cells.
A 2,3-dialkoxynaphthalene-based naphthocage was synthesized. It shows similarly strong binding affinity to organic cations as the 2,6-dialkoxynaphthalene-based naphthocage but different guest preference and conformational response.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
