Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 89-01-0, Name is Pyrazine-2,3-dicarboxylic acid, molecular formula is , belongs to Pyrazines compound.

Pyrido[2,3-b]pyrazine-based full-color fluoresent materials for high-performance OLEDs
High photoluminescence quantum efficiency (PLQY) and simple molecular structure in a full-color emitting material system are two crucial issues for cost-effective multicolor display applications. Herein, a new tailor-made fluorescent core (pyrido[2,3-b]pyrazine) is designed and synthesized. Through systematically fine-tuning the band gap, the versatile pyrido[2,3-b]pyrazine family exhibits a wide range of emissions spanning the entire visible region from blue to red. By reasonable choice of donor units, two thermally activated delayed fluorescence (TADF) molecules are obtained and the resulting OLEDs exhibit a yellow emission and an orange emission with high EQEs of up to 20.0% and 15.4%, respectively.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 89-01-0, in my other articles.
