Control of metallo-supramolecular assemblies via steric, hydrogen bonding and argentophilic interactions; formation of a 3-dimensional polymer of circular helicates

This work shows how multiple non-covalent interactions are employed to control metallosupramolecular architectures and we demonstrate that a ligand, which contains two bidentate domains separated by a ArOH spacer, forms a mesocate when complexed with Ag(I). However, changing this to an ArOCH2CH2Ph spacer unit results in a 1-dimensional helical polymer upon reaction with the same cation. Reaction of Ag(I) with the ArOMe derivative gives a hexanuclear circular helicate which forms inter-assembly Ag⋯Ag interactions resulting in a 3-dimensional honeycomb-like polymer of hexanuclear circular helicates

The 3M Buckley Innovation Centre: A case study of alternative finance for universities from England = El 3M Buckley Innovation Center: Un caso de estudio de financiación alternativa para universidades

The University of Huddersfield is a publicly funded university in West Yorkshire, England, with a mission which covers the spectrum of university activities including teaching, research and engagement with business. The focus of this case study is the 3M Buckley Innovation Centre (3M BIC) in Huddersfield which aims to facilitate business growth, encourage business to academia collaboration, and actively promote innovation. The chapter particularly focuses on the innovation and financial models which the University of Huddersfield has implemented to optimise relationships with industry. The innovation model and impact of the Centre is described in addition to the funding and governance structures which have been implemented to establish and sustain the Centre. National recognition of the unique approach to university-business engagement is also highlighted.ResumenLa Universidad de Huddersfield es una universidad financiada con fondos públicos en West Yorkshire, Inglaterra, con una misión que cubre el espectro de actividades universitarias, incluida la enseñanza, la investigación y el compromiso con las empresas.

Synthesis of Ligands Containing N-oxide Donor Atoms and Their Assembly into Metallosupramolecular Structures.

A series of ligands that contain both N-donor and N-oxide donor atoms have been synthesised and ligands L5, L6, L7 and L8 contain, 4, 6, 5, and 6 donor atoms respectively. The smallest ligand L5 forms a mononuclear complex with Cu2+ ([Cu(L5)(ClO4)2(MeCN)]) whereas L6 and L7 form dinuclear double helicates with Ni2+ and Cu2+ respectively ([Ni2(L6)2]4+ and [Cu2(L7)2]4+ ). L8 forms a tetranuclear cyclic helicate upon reaction with Co2+ ([Co4(L8)4]8+) and in all cases the complexes are characterised by single-crystal X-ray diffraction and ESI-MS. The N-oxide units imparts flexibility in the ligand strand and where the unoxidised ligand strand forms a cyclic helicate, the incorporation of an N-oxide unit allows the formation of the dinuclear double helicate
