The title compound, C(18)H(12)N(2)O(2)·0.5H(2)O, was prepared by the reaction of 1,4-phenyl-enediamine with 1,8-naphthalic anhydride in refluxing dimethyl-formamide. The structure is stabilized by N-H⋯O and O-H⋯O hydrogen bonds. There are π-π stacking inter-actions [centroid-centroid distances of 3.718 (2), 3.510 (2) and 3.546 (2) Å] and C-H⋯π inter-actions between the mol-ecules. The water mol...

ABSTRACT Highly fluorescent and photostable (2-alkyl)-1H-benzo[de]isoquinoline-1,3(2H)-diones with a polymerizable norbornene scaffold have been synthesized and polymerized using ring-opening metathesis polymerization. The monomers presented herein could be polymerized in a living fashion, using different comonomers and different monomer ratios. All obtained materials showed good film-forming p...

Abstract The fabrication of diodes using organic semiconductors as active materials has gained wide interest, and undergone significant progress in the past few decades. A naphthalimide-indole derivative (BNIA) was synthesized through bromination acenaphthene, subsequent oxidation, finally imidation with indole-3-acetic anhydride. molecular structure characterized NMR IR spectroscopy. BNIA disp...

This research is an attempt to measure the effect of alkyl tail on the visible spectra and order parameters S of some azo N-ester-1,8-naphthalimide(ANEN) disperse dyestuff. For the first time, the visible absorption spectra of two azo N-ester-1,8-naphthalimide(ANEN) dyes with identical molecular size and diverse alkyl tails were obtained in liquids and liquid crystalline solvent. Ordinary organ...

With the rapidly increasing interest in the field of glycomics, which is the comprehensive study of the roles carbohydrates play in a living system, urgent need for developing quick and highly selective carbohydrate sensors is growing. The boronic acid group, with its electron-deficient structure (6 valence electrons with an open shell), acts as a Lewis acid with high intrinsic affinity towards...

The photophysical properties of naphthalimide dyes NI1-3 with electron releasing 4-methoxy- (NI1), 3,4-dimethoxystyryl- (NI2) and dimethylaminostyryl (NI3) groups are examined in a variety of protic and aprotic solvents. All compounds demonstrate positive solvatochromism in the steady-state absorption and fluorescence spectra. The analysis of the dependence of the Stokes shift on the polarity o...
