(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 ... -
{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 ... -
5,10-A2B2-Type meso-Substituted Porphyrins A Unique Class of Porphyrins with a Realigned Dipole Moment
(2011)Abstract: Current applications in porphyrin chemistry require the use of unsymmetrically substituted porphyrins. Many current industrial interests in optics and biomedicine require systems with either push-pull (electron ... -
[5,15-Bis(2-methyl-prop-yl)porphyrinato]nickel(II).
(2012)The title compound, [Ni(C28H28N4)], crystallizes with two independent molecules in the unit cell, one of which is located on an inversion center. Both macrocycles exhibit a planar conformation with average deviation ... -
5,15-Bis(4-pentyl-oxyphen-yl)porphyrin.
(2013)In the title compound, C42H42N4O2, the complete molecule is generated by a crystallographic inversion centre. The porphyrin system exhibits a near planar macrocycle conformation with an average deviation from the ... -
(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 ... -
7-Nitro-5,10,15,20-tetraphenylporphyrin Dichloromethane Solvate
(International Union of Crystallography, 1998)The title compound shows significant conformational distortion in the vicinity of the [beta]-nitro group. This is attributed to steric interaction between a meso-phenyl and the [beta]-nitro group. The overall degree of ... -
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 ... -
Aerobic oxidation of NHC-catalysed aldehyde esterifications with alcohols: Benzoin, not the Breslow intermediate, undergoes oxidation
(2013)Benzoin (and neither the Breslow intermediate nor the NHC–aldehyde tetrahedral adduct) has been unambiguously identified as the oxidised species in aerobic NHC-catalyse d aldehyde esterifications. -
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 ...
