Self-assembling porphyrin [2]-catenanes

Using the concepts of self-assembly developed for the construction of topologically complex molecules such as [2]-catenanes and rotaxanes, the syntheses of several prophyrin-catenanes are described. The successful insertion of the porphyrin subunit into [

Enhanced photoelectrochemistry in supramolecular CdS-nanoparticle-stoppered pseudorotaxane monolayers assembled on electrodes

A pseudorotaxane monolayer consisting of a supramolecular complex generated between cyclo-bis(paraquet-p-phenylene), (1), and the 1,4-bis(mercapto ethyloxy ethyl)benzene monolayer, (2), that is stoppered by CdS nanoparticles (3-5 nm) is generated on Au electrodes. The surface coverage of the supramolecular complex units and the associated CdS particles corresponds to 2.4 ?± 0.2 ?? 10-10 mole?·cm-2 and 3 ?? 1012 particles?·cm-2, respectively. The photocurrent generated by the (1)/(2)-CdS pseudorotaxane architecture is 8-fold higher than in a CdS-nanoparticle monolayer system that lacks (1). The enhanced photocurrent in the pseudorotaxane assembly is attributed to vectorial electron transfer of photoexcited conduction-band electrons to the threaded electron acceptor (1), which leads to charge separation and to the retardation of the electron-hole recombination process.

Thermodynamic Synthesis of Rotaxanes by Imine Exchange

(Matrix Presented) By utilizing the dynamic nature of imine bonds, it is possible to construct [2]rotaxanes from a ring and a preformed dumbbell under thermodynamic control. These dynamic [2]rotaxanes, which exhibit reversible supramolecular-like behavior
