Abstract

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.
