Journal ArticleDOI
Tetrathiafulvalene hetero radical cation dimerization in a redox-active [2]catenane.
Cheng Wang,Scott M. Dyar,Dennis Cao,Dennis Cao,Albert C. Fahrenbach,Albert C. Fahrenbach,Noah E. Horwitz,Michael T. Colvin,Raanan Carmieli,Charlotte L. Stern,Sanjeev K. Dey,Michael R. Wasielewski,J. Fraser Stoddart,J. Fraser Stoddart +13 more
TL;DR: EPR titration spectroscopy and simulations reveal that the radical states of the two constitutionally different TTF units in the [2]catenane still experience long-range electronic intramolecular coupling interactions, despite the presence of the CBPQT(4+) ring.
Journal ArticleDOI
Mechanical bonds and topological effects in radical dimer stabilization.
Marco Frasconi,Takashi Kikuchi,Dennis Cao,Yilei Wu,Wei Guang Liu,Scott M. Dyar,Gokhan Barin,Amy A. Sarjeant,Charlotte L. Stern,Raanan Carmieli,Cheng Wang,Cheng Wang,Michael R. Wasielewski,William A. Goddard,William A. Goddard,J. Fraser Stoddart +15 more
TL;DR: The electrochemical behavior of these three radically configurable isomers demonstrates that a fundamental relationship exists between topology and redox properties.
Journal ArticleDOI
Noncovalent Side-Chain Functionalization of Terpolymers
TL;DR: In this article, random poly(norbornene)-based terpolymers containing sulfur−carbon−sulfur (SCS) palladated pincer complexes, dibenzo[24]crown-8 (DB24C8) rings, and diaminopyridine moieties were synthesized by ring-opening metathesis polymerization.
Journal ArticleDOI
Crown ethers as second-sphere ligands. The interactions of transition-metal ammines with 18-crown-6 and dibenzo-18-crown-6
TL;DR: In this paper, neutral and cationic transition-metal ammines interact with crown ethers in aqueous and non-aqueous solution via hydrogen-bond formation to give discrete or polymeric adducts which are readily isolated by crystallisation.
Journal ArticleDOI
Functionally rigid and degenerate molecular shuttles.

TL;DR: Evidence is shown for the formation of mechanically interlocked structures, resulting in the upfield shifts of the resonances for key protons on the dumbbell-shaped components, just as has been observed in the flexible [2]rotaxanes.
