A series of entirely new framework chromeno[4,3,2-de][1,6]naphthyridine derivatives containing carbazole groups have been carefully designed and prepared. The relationship of photoluminescence property and structure of these compounds was systematically investigated via UV-vis, fluorescence and electrochemical analyzer. The HOMO and LUMO distributions of these compounds were calculated by density functional theory (DFT) (B3LYP; 6-31G *) method. These compounds exhibited high fluorescence quantum yields, desirable HOMO levels and high thermal stability, indicating that the combination of chromeno[4,3,2-de][1,6]naphthyridine and carbazole could be an efficient means to enhance hole-transporting ability and fluorescent quantum yield.

A series of entirely new framework chromeno[4,3,2-de][1,6]naphthyridine derivatives containing triphenylamine groups have been carefully designed and prepared in good yields using the Pd(0) catalyzed Suzuki couplings reactions. The relationship of photoluminescence property and structure of these compounds was systematically investigated via thermogravimetric analyzer, UV-vis, fluorescence and electrochemical analyzer. The HOMO and LUMO distributions of these compounds were calculated by density functional theory (DFT) (B3LYP; 6-31G*) method. These compounds exhibited high fluorescence quantum yields, desirable HOMO levels and high thermal stability, indicating that the combination of chromeno[4,3,2-de][1,6]naphthyridine and triphenylamine could be an efficient means to enhance hole-transporting ability and fluorescent quantum yield.
Silica gel-catalyzed one-pot syntheses in water and fluorescence properties studies of 5-amino-2-aryl-3H-chromeno[4,3,2-de]-[1,6]naphthyridine-4- carbonitriles and 5-amino-2-aryl-3H-quinolino-[4,3,2-de][1,6]naphthyridine-4- carbonitriles

The silica gel-catalyzed synthesis of 5-amino-2-aryl-3H-chromeno[4,3,2-de] [1,6]naphthyridine-4-carbonitriles and 5-amino-2-aryl-3H-quinolino[4,3,2-de][1, 6]naphthyridine-4-carbonitriles were simply achieved upon the one-pot cascade reaction of malononitrile with substituted 2-hydroxyacetophenone (or 2-aminoacetophenone) and aromatic aldehyde in aqueous media. The mechanistic investigation results based on electrospray ionization mass spectrometry (ESI-MS) indicated that malononitrile displayed a dual role during this transformation. Thirteen bonds were cleaved and 12 new bonds were constructed in the formation of 5-amino-2-aryl-3H-chromeno[4,3,2-de][1,6]naphthyridine-4- carbonitriles, while only 2 H2O molecules were removed. The fluorescence properties screening showed five new compounds have high fluorescence quantum yields.
