(2,3,7,8,12,13,17,18-Octa-ethyl-5-phenyl-porphyrinato)platinum(II).
(2011)The title compound, [Pt(C42H48N4)], was obtained through metallation of the corresponding free base with PtCl2, followed by crystallization from methylene chloride/methanol. The molecule exhibits an almost planar macrocycle ... -
3-Urea-1,8-naphthalimides are good chemosensors: a highly selective dual colorimetric and fluorescent ICT based anion sensor for fluoride
(2011)he 1,8-naphthalimide sensor 1 was developed as a colorimetric and fluorescent sensor for anions. Being the first example of such anion sensors, where the 3-position of the naphthalimide ring is used to incorporate the anion ... -
3D Printed Sugar-Sensing Hydrogels
(2020)The ability of boronic acids to reversibly bind diols, such as sugars, has been widely studied in recent years. In solution, through the incorporation of additional fluorophores, this boronic acid-sugar interaction can be ... -
{4,6-Bis[(E)-1-methyl-2-(pyridin-2-yl-methyl-idene-κN)hydrazinyl-κN]pyrimidine-κN}dichloridocopper(II) methanol disolvate monohydrate
(2011)The title compound, [CuCl2(C18H18N8)]?2CH3OH?H2O, contains a pentacoordinated Cu(II) atom bonded to the tridentate 4,6-bis[(E)-1-methyl-2-(pyridin-2-ylmethylidene)hydrazinyl]pyrimidine ligand and two Cl atoms. The geometry ... -
(5,15-Dianthracen-9-yl-10,20-dihexyl-porphyrinato)nickel(II): A planar nickel(II) porphyrin
(2010)The title compound, [Ni(C60H52N4)], is an example of a meso tetrasubstituted nickel(II) porphyrin with both meso aryl and alkyl residues. The molecule exhibits a planar macrocycle with an average deviation of the 24 ... -
(5-n-Butyl-10,20-diisobutylporphyrinato)nickel(II).
(2014)The asymmetric unit of the title compound, [Ni(C 32 H 36 N 4 )], contains two independent molecules exhibiting an overall ruffled conformation of the porphyrin macrocycle and differing mainly in the positions of ... -
(5-tert-Butylporphyrinato)copper(II), a nonplanar porphyrin with only one sterically demanding meso residue
(2011)The title compound, [Cu(C24H20N4)], is a rare example of a porphyrin carrying only one substituent. Its crystal structure exhibits two molecules in the asymmetric unit. The bulky meso tert-butyl residue gives rise to a ... -
A2B2-type push-pull porphyrins as reverse saturable and saturable absorbers
(2007)A2B2-type push?pull porphyrins with a strong intramolecular dipole moment have been prepared via Heck and Suzuki coupling reactions as novel materials for use in nonlinear optics (NLO); they display saturable (SA) and ... -
Acceptor Levels in p-Type Cu2O: Rationalizing Theory and Experiment
(2009)Understanding conduction in Cu2O is vital to the optimization of Cu-based p-type transparent conducting oxides. Using a screened hybrid?density-functional approach we have investigated the formation of p-type defects in ... -
Aggregation of dinuclear {Fe2hpdta} units to form polynuclear oxy/hydroxy-bridged Fe(III) coordination complexes.
(2010)An approach for the preparation of oxy/hydroxy briged FeIII clusters that takes advantage of hydrolytic condensations of well defined {Fe2hpdta(H2O)4} building units is presented. Co-ligands such as tripodal H3tea or ... -
Allenylporphyrins: a new motif on the porphyrin periphery
(2009)Palladium-catalysed Suzuki?Miyaura cross-coupling proved to be the simplest and most efficient method for attaching an unsubstituted allene, a novel substituent and potential functional group, to the porphyrin periphery. ... -
Anion-directed supramolecular chemistry modulating the magnetic properties of nanoscopic Mn coordination clusters: From polynuclear high-spin complexes to SMMs
(2016)We report a supramolecular approach to mixed-valent Mn coordination clusters that demonstrates how halide ions can be applied to in fl uence the assembly of distinct tetranuclear building units to produce a number of ... -
Anomalous magnetic field effects during pulsed injection metal-organic chemical vapor deposition of magnetite films
(2010)We report on large external magnetic field effects during pulsed injection metal-organic chemical vapor deposition of magnetite films on MgO 001 . The application of a 1 T field during the growth process significantly ... -
