[ 1 ] - Synthesis and Characterization of Novel Photoactive Poly(ether-amide)s Based on Highly Substituted Phenanthrimidazole
A new aromatic diamine monomer containing ether linkage based on the phenanthrimidazole ring, 1,1´-(4,4´- oxy bis(1,4-phenylene))bis(2-(4-aminophenyl)-1H-phenanthro[9,10-d]imidazole) was synthesized through four-components condensation of 4,4´-diamino diphenyl ether, 4-nitrobenzaldehyde, phenanthrene-9,10-dione and ammonium acetate in presence of acetic acid, followed by palladi...
[ 2 ] - Sulfuric acid immobilized on silica: A versatile and reusable heterogeneous catalyst for the synthesis of phenanthrimidazole derivatives
A new, convenient, efficient, and cost-effective one-pot synthesis of 1Hphenanthro[9,10]imidazol-2-yl from phenanthraquinone and aldehydes, using sulfuric acidimmobilized on silica as catalyst is described. The present methodology offers severaladvantages such as excellent yields, simple procedure, shorter reaction times, the use ofinexpensive reagents, easy recovery and eco-friendly. In additi...
[ 3 ] - 4-Aryl-2, 6-di(pyren-1-yl)pyridines: A facile procedure for synthesis and studying of fluorescence properties
Pyrene and its derivatives exhibit thermal stability, high extinction coefficients, excimer formation, high photoluminescence, long fluorescence lifetime, fluorophoric properties and enhanced charge carrier mobility which make them find applications in optoelectronic area and are useful as large planar synthetic building blocks in supramolecular chemistry. One of the approaches to overcome this...
