A bifunctionalized [3]rotaxane and its incorporation into a mechanically interlocked polymer.
A novel bifunctionalized [3]rotaxane based on a triptycene-derived macrotricyclic host was conveniently synthesized. On the basis of the [3]rotaxane, a linear main-chain poly[3]rotaxane was further obtained by the highly efficient Huisgen 1,3-dipolar cycloaddition.
متن کاملOrganometallic rotaxane dendrimers with fourth-generation mechanically interlocked branches.
Mechanically interlocked molecules, such as catenanes, rotaxanes, and knots, have applications in information storage, switching devices, and chemical catalysis. Rotaxanes are dumbbell-shaped molecules that are threaded through a large ring, and the relative motion of the two components along each other can respond to external stimuli. Multiple rotaxane units can amplify responsiveness, and rep...
متن کاملA mechanically interlocked bundle.
The prototype of an artificial molecular machine consisting of a trisammonium tricationic component interlocked with a tris(crown ether) component to form a molecular bundle with averaged C(3v) symmetry has been designed and synthesized. The system is based on noncovalent interactions, which include 1) N(+)-H...O hydrogen bonds; 2) C-H...O interactions between the CH(2)NH(2) (+)CH(2) protons on...
متن کاملFörster resonance energy transfer by formation of a mechanically interlocked [2]rotaxane.
A [2]rotaxane has been constructed from a di-pyrene appended pillar[5]arene wheel, a pyridinium axle, and a perylene stopper. It shows efficient Förster resonance energy transfer from pyrene to perylene by formation of a mechanically interlocked [2]rotaxane.
متن کاملA molecular pulley based on a triply interlocked [2]rotaxane.
A novel triply interlocked [2]rotaxane based on a triptycene-derived tris(crown ether) host and a guest embedded with three dibenzylammonium and three N-methyltriazolium recognition sites was designed and synthesized, which showed pulley-like shuttling motion controlled by acid and base.
