In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Formula: C4H2Cl2N2, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 141-30-0, name is 3,6-Dichloropyridazine. In an article，Which mentioned a new discovery about 141-30-0
Two organic materials incited by electron deficiency of a pyridazine moiety were designed for application as bipolar host materials of phosphorescent organic light-emitting diodes. Modification of the pyridazine moiety with carbazole and pyrrolocarbazole hole transport units provided 3,6-bis(2-(9H-carbazol-9-yl)phenyl)pyridazine (CzPd) and 3,6-bis(2-(3-phenylpyrrolo[3,2-a]carbazol-10(3H)-yl)phenyl)pyridazine (PCzPd) as bipolar host materials. The 3,6-bis(2-(9H-carbazol-9-yl)phenyl)pyridazine and 3,6-bis(2-(3-phenylpyrrolo[3,2-a]carbazol-10(3H)-yl)phenyl)pyridazine were high triplet energy hosts by ortho- substitution of the hole transport units. Based on the triplet energy of the host materials, green phosphorescent organic light-emitting diodes were devised and the green devices presented high quantum efficiency of 15.5%
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 141-30-0, help many people in the next few years.Formula: C4H2Cl2N2
