(2014)The synthesis and characterisation of five bis-1,8-naphthalimide containing Tröger's bases 1–5 formed from their corresponding 3-amino-1,8-naphthalimide precursors 6–10 is described. The photophysical investigations of 1–5 ... -
Synthesis, crystal structure and EPR spectroscopic analysis of novel copper complexes formed from N-pyridyl-4-nitro-1,8-naphthalimide ligands
(2014)The mono-dentate, pyridyl containing, nitro naphthalimide ligands N-(4-pyridyl)-4-nitro-1,8-naphthalimide (L1) and N-(3-pyridyl)-4-nitro-1,8-naphthalimide (L2) were prepared and complexed with a selection of copper salts ... -
Self-assembly formation of mechanically interlocked [2]- and [3]catenanes using lanthanide ion [Eu(iii)] templation and ring closing metathesis reactions
(2014)The formation of interlocked lanthanide-based catenanes using Eu(III)-directed synthesis is described (catenation being achieved via a ring-closing metathesis reaction); the self-assembly formation of the supramolecular ... -
The btp [2,6-bis(1,2,3-triazol-4-yl)pyridine] binding motif: A new versatile terdentate ligand for supramolecular and coordination chemistry
(2014)Ligands containing the btp [2,6-bis(1,2,3-triazol-4-yl)pyridine] motif have appeared with increasing regularity over the last decade. This class of ligands, formed in a one pot ‘click’ reaction, has been studied for various ... -
Supramolecular pyridyl urea gels as soft matter with antibacterial properties against MRSA and/or E. coli
(2014)The synthesis and characterisation of novel aryl-pyridyl ureas are described, which form self-assembly structures via extended hydrogen bonding and π–π interactions in the solid state, and in selected cases, form supramolecular ... -
Pushing the limit: synthesis, photophysical and DNA binding studies of a NIR-emitting Ru(II)-polypyridyl probe with 'light switch' behaviour
(2012)The new Ru(II) polypyridyl complex 1 was synthesised using microwave irradiation from the new polypyridyl ligand 2 ‘DipyTAP’, and its photophysical properties, and DNA binding abilities were investigated using various ... -
Recent advances in the development of 1,8-naphthalimide based DNA targeting binders, anticancer and fluorescent cellular imaging agents.
(2013)The development of functional 1,8-naphthalimide derivatives as DNA targeting, anticancer and cellular imaging agents is a fast growing area and has resulted in several such derivatives entering into clinical trials. This ... -
High-Performance Sensors Based on Molybdenum Disulfide Thin Films
(2013)High-performance sensors based on molybdenum disulfide (MoS2) grown by sulfurization of sputtered molybdenum layers are presented. Using a simple integration scheme, it is found that the electrical conductivity of MoS2 ... -
Functionalisation of graphene surfaces with downstream plasma treatments
(2013)We report on an adjustable process for the functionalisation of graphene surfaces with a downstream plasma source. The parameters of oxygen plasma treatments are modified such that oxygenated functionalities can be added ... -
Highly sensitive, transparent, and flexible gas sensors based on gold nanoparticle decorated carbon nanotubes
(2013)We report on a high performance flexible and transparent chemical sensor based on functionalised single-walled carbon nanotubes (SWCNTs). The SWCNT films were spray-deposited on transparent and flexible plastic substrates, ... -
Report on the Special Miniworkshop "nano&Management"
(2013)This is a short report on a special workshop on matters “around” science, held during the Kirchberg Winterschool 2013 on Electronic Properties of Novel Materials. The topics discussed are patents, experiences of small ... -
"The dominant role of the solvent-water interface in water droplet templating of polymers"
(2013)We investigate the formation of microstructured polymer networks known as Breath Figure templated structures created by the presence of water vapour over evaporating polymer solutions. We use a highly controlled experimental ... -
The electronic structure of silver orthophosphate: Experiment and theory
(2014)Since the original discovery of the water-splitting activity of silver orthophosphate (Ag3PO4), considerable effort has been devoted to improving its photocatalytic activity and stability through morphology control and the ... -
Occupation matrix control of d- and f-electron localisations using DFT + U.
(2014)The use of a density functional theory methodology with on-site corrections (DFT + U ) has been repeatedly shown to give an improved description of localised d and f states over those predicted with a standard DFT ... -
Valence-band density of states and surface electron accumulation in epitaxial SnO2 films
(2014)The surface band bending and electronic properties of SnO 2 (101) films grown on r -sapphire by plasma-assisted molecular beam epitaxy have been studied by Fourier-transform infrared spectroscopy (FTIR), x-ray ... -
Ceria co-doping: Synergistic or average effect?
(2014)Ceria (CeO2) co-doping has been suggested as a means to achieve ionic conductivities that are significantly higher than those in singly doped systems. Rekindled interest in this topic over the last decade has given rise ... -
Understanding doping anomalies in degenerate p-type semiconductor LaCuOSe
(2014)The failure to develop a degenerate, wide band gap, p-type oxide material has been a stumbling block for the optoelectronics industry for decades. Mg-doped LaCuOSe has recently emerged as a very promising p-type anode ... -
Valence States in CeVO4 and Ce0.5Bi0.5VO4 Probed by Density Functional Theory Calculations and X-ray Photoemission Spectroscopy
(2014)Ce is one of the few lanthanide elements to exhibit well-defined (III) and (IV) oxidation states in solid state environments and there is therefore ambiguity as to whether CeVO4 should be formulated as Ce(III)V(V)O4 or ... -
The nature of oxygen states on the surfaces of CeO2 and La-doped CeO2
(2014)The oxygen states on CeO2 surfaces were investigated with DFT+U calculations. The results reveal the variable nature of the oxygen states, including the never before modelled intrinsic peroxide surface defect. Under ... -
Interface stoichiometry control to improve device voltage and modify band alignment in ZnO/Cu2O heterojunction solar cells
(2014)The interface stoichiometry of cuprous oxide (Cu2O) prepared by thermal oxidation was controlled by adjusting the O2 and Zn partial pressures during ZnO sputter deposition and measured by high-resolution X-ray photoelectron ...
