The complexes of the formula Ln(carb)3(H2O)2 (where Ln = Eu, Tb, Gd, La, Yb; carb = various pyrazolecarboxylic acids) were synthesized and thoroughly characterized. It was shown that the quantum yields of terbium complexes depend mainly on the type of substituents of the ligand, while the quantum yields of europium complexes are influenced by the ligand isomerism due to the presence or absence of the ligand-to-metal charge transfer (LMCT) state. These compounds were successfully tested as bioimaging probes as well as OLED emitting layers due to their high photo- and electroluminescent performance. In the experiment, the researchers used many compounds, for example, 1-Methyl-5-phenyl-1H-pyrazole-3-carboxylic acid (cas: 10199-53-8Safety of 1-Methyl-5-phenyl-1H-pyrazole-3-carboxylic acid).
1-Methyl-5-phenyl-1H-pyrazole-3-carboxylic acid (cas: 10199-53-8) belongs to pyrazole derivatives. Pyrazole and its derivatives are considered a pharmacologically important active scaffold that possesses almost all types of pharmacological activities. Pyrazole rings have been used as core components of several leading non-steroidal anti-inflammatory drugs (NSAIDs) and antihypertensive drugs. It has also been found to be useful as a bifunctional ligand for metal catalysis.Safety of 1-Methyl-5-phenyl-1H-pyrazole-3-carboxylic acid
