The effect of acceptor structure on emission color tuning in organic semiconductors with D-π-A-π-D structures was written by Ledwon, Przemyslaw;Wiosna-Salyga, Gabriela;Chapran, Marian;Motyka, Radoslaw. And the article was included in Nanomaterials in 2019.Application of 148231-12-3 This article mentions the following:
A series of novel donor-acceptor D-π-A-π-D compounds were synthesized and characterized in order to determine the influence of different acceptor units on their properties. The introduction of acceptor moieties had a direct impact on the HOMO and LUMO energy levels. Fluorescence spectra of compounds can be changed by the choice of an appropriate acceptor and were shifted from the green to the near-IR part of spectra. Due to observed concentration induced emission quenching, the green exciplex type host was used to evaluate the potential of synthesized mols. as emitters in organic light emitting diodes (OLEDs). In the experiment, the researchers used many compounds, for example, 5,8-Dibromoquinoxaline (cas: 148231-12-3Application of 148231-12-3).
5,8-Dibromoquinoxaline (cas: 148231-12-3) belongs to pyrazine derivatives. Pyrazine heterocycles and their benzo derivatives possess many interesting properties, including chemical reactivity profiles, and have diverse applications in total synthesis, medicine, chemical biology, materials, dyes, and imaging. Substituted pyrazines have been found as subunits of multiple synthetically constructed therapeutic agents, as well as several natural products.Application of 148231-12-3
