Journal of the American Chemical Society

Kim DS, Lynch VM, Park JS, Sessler JL.
PMID: 24011216
J Am Chem Soc. 2013 Oct 02;135(39):14889-94. doi: 10.1021/ja4080198. Epub 2013 Sep 19.

During the past several decades, considerable effort has focused on self-assembled systems. However, most work has been directed toward understanding the equilibrium between two major chemical entities, namely the dissociated components and the corresponding associated complex. While there are...

Phys Rev Lett. 2017 Sep 15;119(11):115501. doi: 10.1103/PhysRevLett.119.115501. Epub 2017 Sep 14.

Using single-crystal x-ray diffraction we characterize the 235 K incommensurate phase transition in the hybrid molecular framework tetraethylammonium silver(I) dicyanoargentate, [NEt_{4}]Ag_{3}(CN)_{4}. We demonstrate the transition to involve spontaneous resolution of chiral [NEt_{4}]^{+} conformations, giving rise to a state in...
