Novel biomimetic mononuclear complexes, [Fe()Cl2](+) () and [Cu()(H2O)](2+) () based on naphthalimide appended tripodal tetradentate ligand ( = 2,2',2''-(3,3',3''-(2,2',2''-nitrilotris(methylene)tris(1H-benzo[d]imidazole-2,1-diyl))tris(propane-3,1-diyl))tris(1H-benzo-[de]isoquinoline-1,3(2H)-dione)) have been synthesized and characterized by various analytical and spectral techniques. In additi...

Naphthalene-diimide (NDI)-derived building blocks have been explored extensively for supramolecular assembly as they exhibit attractive photophysical properties, suitable applications in organic optoelectronics. Core-substituted derivatives of the NDI chromophore (cNDI) differ significantly from parent dye terms optical and redox properties. Adequate molecular engineering opportunities substitu...

In this study, a series of N-naphthalimide ester derivatives (noted NPIE1-NPIE9) with different substituents were designed as visible light photoinitiators (PIs). These structures exhibited good absorption properties in the range. Photoinitiation abilities NPIEs evaluated upon exposure to light-emitting diode at 405 nm. All demonstrated performances free radical polymerization acrylate monomers...

A fluorescent sensor for halogenated solvents termed AMN is reported. AMN shows strong fluorescence in most halogenated solvents (QE > 0.1) but weak fluorescence (QE<0.01) in most non-halogenated solvents. In chlorinated solvents, the fluorescence intensity decreased with the reduction of chlorine content. On the contrary, in brominated solvents the fluorescence intensity increased with the red...

New photoswitchable pyridyl-azo-phenyl-decorated tripodal host ligands (Laz) that belong to the cyclotriveratrylene family have been synthesized, and their photoswitching behavior crystal structures determined. The latter includes a remarkable 7-fold Borromean-weave entanglement of π–π stacked layers. Trigonal bipyramidal {[Pd(en)]3(Laz)2}6+ metallo-cryptophanes (en = ethylenediamine) were form...
