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 MXene Architectures for Efficient Energy Storage and Conversion
(2020)2D transition metal carbides and/or nitrides (MXenes), by virtue of high electrical conductivity, abundant surface functional groups and excellent dispersion in various solvents, are attracting increasing attention and ... -
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 ... -
The 4-pyridonyl group as a multifunctional electron donor in 1,8-naphthalimide-based photoluminescent and mechanically interlocked coordination compounds
(2018)A new ligand system incorporating the 4-pyridonyl group as a substituent in 1,8-naphthalimide compounds is presented, with the pyridone group acting as both an electron donor for the internal charge transfer (ICT) fluorescence ... -
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 ... -
