Predictable color tuning in multicomponent photoluminescent (PL) systems is achieved using mixtures of simultaneously emitting organic mols. By mitigating the potential for energy transfer through the control of concentration, the resulting emission chromaticity of five dichromic PL systems is approximated as a linear combination of the emitting components and their corresponding brightness (χi, φi, and Iex,i). Despite being limited to dilute solutions (10-6 M), color tuning within these systems was controlled by (1) varying the composition of the components and (2) exploiting the differences in the components’ excitation intensities at common wavelengths. Using this approach, white light emission (WLE) was realized using a pre-determined mixture of red, green, and blue emitting organic mols. Based on these results, materials and devices with built-in or programmable emission color can be achieved, including highly sought-after WLE. This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0Category: thiazole).
3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0) belongs to thiazole derivatives. Thiazole rings are planar and aromatic. Thiazoles are characterized by larger pi-electron delocalization than the corresponding oxazoles and have therefore greater aromaticity. Electrophilic attack at nitrogen depends on the presence of electron density at nitrogen as well as the position and nature of substituent linked to the thiazole ring.Category: thiazole
