The mixing of circular helicates derived from different amines led to the complete exchange of the N-alkyl residues on the periphery of the metallo-supramolecular scaffolds over 4 days in DMSO at 60 °C. Under similar conditions, deuterium-labeled and nonlabeled building blocks showed full dialdehyde building block exchange over 13 days for open circular helicates but was much slower for the analogous closed-loop pentafoil knot (>60 days). Although both knots and open circular helicates self-assemble under thermodynamic control given sufficiently long reaction times, this is significantly longer than the time taken to afford the maximum product yield (2 days). Highly effective error correction occurs during the synthesis of imine-based pentafoil molecular knots and pentameric circular helicates despite, in practice, the systems not operating under full thermodynamic control. -
Weak Functional Group Interactions Revealed Through Metal-Free Active Template Rotaxane Synthesis
ARTICLE https://doi.org/10.1038/s41467-020-14576-7 OPEN Weak functional group interactions revealed through metal-free active template rotaxane synthesis Chong Tian 1,2, Stephen D.P. Fielden 1,2, George F.S. Whitehead 1, Iñigo J. Vitorica-Yrezabal1 & David A. Leigh 1* 1234567890():,; Modest functional group interactions can play important roles in molecular recognition, catalysis and self-assembly. However, weakly associated binding motifs are often difficult to characterize. Here, we report on the metal-free active template synthesis of [2]rotaxanes in one step, up to 95% yield and >100:1 rotaxane:axle selectivity, from primary amines, crown ethers and a range of C=O, C=S, S(=O)2 and P=O electrophiles. In addition to being a simple and effective route to a broad range of rotaxanes, the strategy enables 1:1 interactions of crown ethers with various functional groups to be characterized in solution and the solid state, several of which are too weak — or are disfavored compared to other binding modes — to be observed in typical host–guest complexes. The approach may be broadly applicable to the kinetic stabilization and characterization of other weak functional group interactions. 1 Department of Chemistry, University of Manchester, Manchester M13 9PL, UK. 2These authors contributed equally: Chong Tian, Stephen D.

Chemistry allows you create things that never He made chemistry seem fun and exciting. There were and to change the world and change society, were several others from my class who went on and that’s an amazing thing. James Clerk Maxwell, to do chemistry. Barry Moore, on the chemistry the 19th century Scottish physicist, came up with faculty at Strathclyde, also went to my high school. the theory that light was really electromagnetic radiation. A feat of which Richard Feynman said, What motivated you to study molecular machines? ‘…ten thousand years from now - there can be little I worked in Fraser Stoddart’s group before he doubt that the most significant event of the 19th made any catenanes or rotaxanes. We made our century will be judged as Maxwell’s discovery of first catenane about five years after Fraser did. I the laws of electrodynamics.’ I think there are still could see that there was nothing interesting about those kinds of things to be discovered and there is a catenane or a rotaxane in itself. The interesting still that impact to be had on society. thing about them is the possibility to control a well-defined, large-amplitude motion. That’s How long have you been a magician? what you need to make a molecular machine. -

Making Molecular Machines
CONVERSATIONS WITH SCIENTISTS David A. Leigh: Making Molecular Machines "In the field of molecular machines I think the most important development of the last 20 years is the understanding of how to get directional motion from random Brownian motion. It is the key to making molecular motors and, ultimately, all sophisticated molecular machines." University of Manchester David A. Leigh is a Royal Society Research Professor and, since 2014, the Sir Samuel Hall Chair of Chemistry at the University of Manchester in the United Kingdom. Born in 1963 in Birmingham, England, Leigh earned a bachelor's degree in chemistry from the UK's University of Sheffield in 1984 and received a Ph.D from the same institution in 1987. For the next two years, Leigh worked as a postdoctoral research associate at the National Research Council of Canada in Ottawa. He returned to Britain in 1989 to lecture in organic chemistry at the University of Manchester Institute of Science and Technology. In 1998, Leigh moved on to a chair in synthetic chemistry at the University of Warwick and, in 2001 accepted a chair in organic chemistry at the University of Edinburgh. In 2012, Leigh joined the University of Manchester faculty. Leigh is the recipient of numerous honors and awards. He has received research fellowships from the Engineering and Physical Science Research Council and from the European Research Council. His awards include the Feynman Prize for Nanotechnology, the Descartes Prize for Research, and several awards from the Royal Society of Chemistry. He is a fellow of such prestigious associations as the Royal Society of London and the Academia Europaea. -

The Royal Society of Chemistry Presidents 1841 T0 2021
The Presidents of the Chemical Society & Royal Society of Chemistry (1841–2024) Contents Introduction 04 Chemical Society Presidents (1841–1980) 07 Royal Society of Chemistry Presidents (1980–2024) 34 Researching Past Presidents 45 Presidents by Date 47 Cover images (left to right): Professor Thomas Graham; Sir Ewart Ray Herbert Jones; Professor Lesley Yellowlees; The President’s Badge of Office Introduction On Tuesday 23 February 1841, a meeting was convened by Robert Warington that resolved to form a society of members interested in the advancement of chemistry. On 30 March, the 77 men who’d already leant their support met at what would be the Chemical Society’s first official meeting; at that meeting, Thomas Graham was unanimously elected to be the Society’s first president. The other main decision made at the 30 March meeting was on the system by which the Chemical Society would be organised: “That the ordinary members shall elect out of their own body, by ballot, a President, four Vice-Presidents, a Treasurer, two Secretaries, and a Council of twelve, four of Introduction whom may be non-resident, by whom the business of the Society shall be conducted.” At the first Annual General Meeting the following year, in March 1842, the Bye Laws were formally enshrined, and the ‘Duty of the President’ was stated: “To preside at all Meetings of the Society and Council. To take the Chair at all ordinary Meetings of the Society, at eight o’clock precisely, and to regulate the order of the proceedings. A Member shall not be eligible as President of the Society for more than two years in succession, but shall be re-eligible after the lapse of one year.” Little has changed in the way presidents are elected; they still have to be a member of the Society and are elected by other members.
