New pyrrolopyridazine derivatives were synthesized as potential blue organic luminophors. Three different classes of pyrrolopyridazine derivatives were made, for example, aryl groups directly connected to the core PPY (pyrrolo[1,2-b]pyridazine-5,6,7-tricarboxylic acid trimethyl ester) moiety, aryl groups connected to the PPY via a vinylene linker and aryl groups connected to the PPY via an acetylene linker. Their optical and electrochemical properties were productively compared. One of the derivatives 2 showed a relative quantum yield as high as 0.9. Compound 8 in the vinyl bridged pyrrolopyridazine series has been characterized by its X-ray crystal structure analysis.

A general ruthenium(II)-catalyzed methodology enabling the (hetero)arylation of alkenylic C-H bonds utilizing a series of synthetically appealing diazines as directing groups is presented. Despite the presence of additional nitrogen lone pairs remote from

4-Methyl- and 4,6-dimethylpyrimidines, methyl- and 2,5-dimethylpyrazines, as well as 3-methylpyridazine readily react with aromatic aldehydes in a hot solution of sodium hydroxide in the presence of a catalytic amount of a quaternary ammonium salt and in

In order to investigate the effect that additional nitrogen substitution in the 4'-hydroxystyrylpyridine system would have on the photophysical properties of this molecule, we have synthesized a series of four isomeric 4'-hydroxystyryldiazines: the 2,4-di
