Ligand-induced chirality and optical activity in semiconductor nanocrystals: theory and applications
(Walter de Gruyter GmbH, 2020)Chirality is one of the most fascinating occurrences in the natural world and plays a crucial role in chemistry, biochemistry, pharmacology, and medicine. Chirality has also been envisaged to play an important role in ... -
Ligand-Targeted Delivery of Photosensitizers for Cancer Treatment
(2020)Photodynamic therapy (PDT) is a promising cancer treatment which involves a photosensitizer (PS), light at a specific wavelength for PS activation and oxygen, which combine to elicit cell death. While the illumination ... -
Light-harvesting, 3rd generation RuII/CoII MOF with a large, tubular channel aperture
(2019)A photoactive, hetero-metallic CoII/RuII-based metal–organic framework (MOF) with a large channel aperture, ca. 21 Å, is reported. The photophysical properties of the MOF are derived from the RuII nodes giving rise to ... -
Local chemical composition of nanophase-separated polymer brushes
(2011)Using scattering scanning nearfield infrared microscopy (s-SNIM), we have imaged the nanoscale phase separation of mixed polystyrenepoly(methyl methacrylate) (PSPMMA) brushes and investigated changes in the top layer as a ... -
Long-lived excited state dynamics of i-motif structures probed by time-resolved infrared spectroscopy
(2016)UV‐generated excited states of cytosine (C) nucleobases are precursors to mutagenic photoproduct formation. The i‐motif formed from C‐rich sequences is known to exhibit high yields of long‐lived excited states following ... -
Low overpotential high activity manganese/ruthenium mixed oxide electrocatalysts for oxygen evolution in alkaline media.
(2015)The combination of a platinum group material (i.e. ruthenium) with a first row transition metal (i.e. manganese) could provide stability and lower the cost of OER electrocatalyst, while still ... -
Low valent carbonylvanadium complexes of the triphosphorus macrocycle 12[ane]P3Et3.
(2003)The triphosphorus macrocycle 1,5,9-triethyl-1,5,9-triphosphacyclododecane, 12[ane]P3Et3, reacts with [V(CO)6]− under photolytic conditions to produce fac-[(12[ane]P3Et3)V(CO)3]− (1) which has been isolated as its Et4N salt. ... -
Low-humidity sensing properties of multi-layered graphene grown by chemical vapor deposition
(2020)Humidity sensing is fundamental in some applications, as humidity can be a strong interferent in the detection of analytes under environmental conditions. Ideally, materials sensitive or insensitive towards humidity are ... -
Low-temperature synthesis and electrocatalytic application of large-area PtTe2thin films
(2020)The synthesis of transition metal dichalcogenides (TMDs) has been a primary focus for 2D nanomaterial research over the last 10 years, however, only a small fraction of this research has been concentrated on transition ... -
Low-temperature synthesis and investigation into the formation mechanism of high quality Ni-Fe layered double hydroxides hexagonal platelets
(2018)This paper describes the wet-chemistry synthesis of highly crystalline hexagonal fakes of Ni-Fe layered double hydroxide (LDH) produced at temperature as low as 100°C. The fakes with diameter in the range of 0.5–1.5μm ... -
Luminescence anion sensing via modulation of MLCT emission from a naphthalimide-Ru(II)-polypyridyl complex
(2010)The selective sensing of fluoride (F?; an important breakdown product of some chemical warfare agents such as sarin) was achieved by observing quenching in the Metal to Ligand Charge Transfer (MLCT) emission of the ... -
Luminescent lanthanide (Eu(iii)) cross-linked supramolecular metallo co-polymeric hydrogels: The effect of ligand symmetry
(2019)Two lanthanide luminescent naphthyl-dipicolinic amide (dpa) methacrylate monomers for the synthesis of grafted supramolecular co-polymer gels (hydrogels), and their use as additional crosslinks in robust covalently ... -
Luminescent self-assembly formation on a gold surface observed by reversible 'off-on' switching of Eu(III) emission
(2009)The formation of a self-assembly between a sensitising antenna and an Eu(III) functionalised cyclen complex 1.Eu, tethered to a gold surface via a C(12) alkyl thiol spacer, is described where changes in the Eu(III) emission ... -
