Luminescent cyanometallate [Ir(ppy)2(CN)2]– (ppy = C6H5C5H4N) has recently gained attention due to its desired photophysical properties. Our research group reported that the shown a negative solvatochromism like [Ru(bipy)(CN)4]2–, resulting in blue-shift of UV-Vis absorption bands water. Therefore, gain insight into specific solvent-solute interaction governed by hydrogen bond solvation hydrati...

The 1,3a,6a-triazapentalene (TAP) is an aromatic heterocyclic fluorescent dye with interesting features such as its small size, large Stokes shift, solvatochromism, and emission wavelengths that are spread across the visible spectrum. TAPs have been synthesized via different synthetic strategies involving click?cyclization?aromatization domino reactions, gold-catalyzed cyclization of propargyl ...

A concise highlight of the main types chromophoric systems obtained in authors’ and other laboratories through biomimetic chemistry or synthetic manipulation nature-inspired o-quinones is primary focus this Minireview. Following oxidative conversion a variety natural catechol substrates like DOPA, dopamine, 5-S-cysteinyldopa caffeic acid, presence suitable additives, remarkable can be produced,...

White-light emission from single molecular systems has attracted a great deal of attention due to their advantages over multicomponent emitters. Azaheterocyclic push-pull derivatives have been demonstrated be white emitters by combining neutral and protonated forms in the appropriate ratio, although limited cases white-light reported quinazoline derivatives. Herein, we describe series 4-substit...
