A light-stimulated molecular switch driven by radical–radical interactions in water
A redox-controllable bistable rotaxane has been synthesized using templation and click chemistry. With assistance from a sacrificial electron donor, light-triggered switching through numerous cycles can be initiated by ...
Solid-state structures and superstructures of two charged donor-acceptor rotaxanes
Two rotaxanes and a pseudorotaxane containing 1,5-dioxynaphthalene recognition sites located in the middle of their dumbbell and thread components, respectively, and encircled by single cyclobis(paraquat-p-phenylene) ...
pH-operated nanopistons on the surfaces of mesoporous silica nanoparticles
The development of drug delivery systems for the targeted and on-demand release of pharmaceutical products has risen rapidly to become a contemporary challenge in the field of nanobiotechno ...
Autonomous in vitro anticancer drug release from mesoporous silica nanoparticles by pH-sensitive nanovalves
Mesoporous silica nanoparticles (MSNP) have proven to be an extremely effective solid support for ...
Degenerate rotaxanes with electrostatic barriers
A synthetic approach to the preparation of rotaxanes (1–5·6PF6) incorporating bispyridinium derivatives and two 1,5-dioxynaphthalene (DNP) units situated in the rod portions of their dumbbell components that are encircled ...
