Restricting shuttling in bis(imidazolium)…pillar[5]arene rotaxanes using metal coordination (2018)
Journal Article
Langer, P., Yang, L., Pfeiffer, C. R., Lewis, W., & Champness, N. R. (2018). Restricting shuttling in bis(imidazolium)…pillar[5]arene rotaxanes using metal coordination. Dalton Transactions, 48(1), 58-64. https://doi.org/10.1039/c8dt04096f

Metal coordination to a series of bis(imidazolium)…pillar[5]arene [2]rotaxanes through the formation of metal-carbene bonds facilitates a new strategy to restrict the shuttling motion in [2]rotaxanes. Whereas the pillar[5]arene macrocycle rapidly shu... Read More about Restricting shuttling in bis(imidazolium)…pillar[5]arene rotaxanes using metal coordination.

Thionated perylene diimide–phenothiazine dyad: synthesis, structure, and electrochemical studies (2018)
Journal Article
Pearce, N., Davies, E. S., Lewis, W., & Champness, N. R. (2018). Thionated perylene diimide–phenothiazine dyad: synthesis, structure, and electrochemical studies. ACS Omega, 3(10), 14236-14244. https://doi.org/10.1021/acsomega.8b02457

Perylene diimides (PDIs) are promising candidates for n-type semiconductor materials and, thus, for use in organic electronics. Thionation of the imide moiety provides an e?cient strategy to control the donor?acceptor gap of these types of compounds...

Controlling the two-dimensional self-assembly of functionalized porphyrins via adenine–thymine Quartet formation (2018)
Journal Article
Blunt, M. O., Hu, Y., Toft, C. W., Slater, A. G., Lewis, W., & Champness, N. R. (2018). Controlling the two-dimensional self-assembly of functionalized porphyrins via adenine–thymine Quartet formation. Journal of Physical Chemistry C, 122(45), 26070-26079. https://doi.org/10.1021/acs.jpcc.8b08888

The development of supramolecular synthons capable of driving hierarchical two-dimensional (2D) self-assembly is an important step toward the growth of complex and functional molecular surfaces. In this work, the formation of nucleobase quartets cons... Read More about Controlling the two-dimensional self-assembly of functionalized porphyrins via adenine–thymine Quartet formation.

Influence of hydrogen-bonding interactions on nuclearity and structure of palladium tiara-like complexes (2018)
Journal Article

The effects of using low-weight alcohols, methanol and ethanol, for the synthesis of MIL-53(Al) are investigated and the results directly compared with analogous synthesis in water and N,N-dimethylformamide (DMF). When methanol is employed in the syn... Read More about Synthesis of hydrophobic MIL-53(Al) nanoparticles in low molecular weight alcohols: systematic investigation of solvent effects.

Protecting-group-free site-selective reactions in a metal–organic framework reaction vessel (2018)
Journal Article
Huxley, M. T., Burgun, A., Ghodrati, H., Coghlan, C. J., Lemieux, A., Champness, N. R., …Sumby, C. J. (2018). Protecting-group-free site-selective reactions in a metal–organic framework reaction vessel. Journal of the American Chemical Society, 140(20), https://doi.org/10.1021/jacs.8b02896

Site-selective organic transformations are commonly required in the synthesis of complex molecules. By employing a bespoke metal-organic framework (MOF, 1·[Mn(CO)3N3]), in which coordinated azide anions are precisely positioned within 1D channels, w...
