May 13, 2024 · We report the synthesis of two rotaxanes (1 and 2) whose rings have appended thiourea units for the selective recognition of Cl− anions. Two-dimensional exchange spectroscopy indicates the ring can shuttle much faster within rotaxanes featuring an axle similar to the one in 1 than in 2 when investigated in solution. Furthermore, rotaxane 1 transports Cl− anions across lipid bilayers more ...
May 3, 2024 · To address this issue, we herein introduce mechanical bond to comprehensively improve the mechanical properties of graphene films, utilizing [2]rotaxane as the bridging unit. Under external force, the [2]rotaxane cross-link undergoes intramolecular motion, releasing hidden chain and increasing the interlayer slip distance between graphene ...
May 18, 2024 · The authors discuss the capabilities of rotaxane actuators to improve the efficiency of drug delivery systems, enabling them to release multiple molecules. 1 Specifically, this discovery marks the first time investigators have been able to show the ability of rotaxane actuators to release more than one component, making it one of the most efficient release systems to date.
May 13, 2024 · Rotaxane-based molecular shuttles using their motion to move cargo within lipid bilayers could be used to position probes and actuators at specific membrane regions, enabling new ways to study and modulate biological and artificial membranes. As an initial step towards that goal, we designed a rotaxane whose ring is decorated with two azobenzene photoswitches. We investigated its operation in ...

May 3, 2024 · Figure 1: Structure of a rotaxane [2] . Specific to the synthesis was the use of boron to form the final product. Boron offers properties favorable to the formation of the rotaxane. Coordinated bonds are formed that facilitate threading. The research can reveal the influence of boron on the properties and structure of the rotaxane.
2 days ago · Dymaxion world map with continental landmasses (I,II,III,IV) and largest islands (1–30) roughly to scale. This list of islands by area includes all islands in the world larger than 2,500 km 2 (970 sq mi) and most of the islands over 1,000 km 2 (390 sq mi), sorted in descending order by area.
