Heterocyclic organic and organometallic compounds (e.g. polypyrrole), and their derivatives, have been of great interest for conductive polymers due to their novel properties and environmental stability as compared to non-aromatic analogs (e.g. polyacetylene). Our current interests focus upon the potential role of pyridazines in next generation electronic devices that utilize organics as the semiconducting material. Pyridazines, 6-membered aromatic rings with two adjacent nitrogens, are promising candidates for a variety of materials and commercial applications. These molecular electronic materials posses several advantages over traditional inorganic semiconducting materials including lower cost of production, higher processibility, and the ability to function on flexible substrates (so called “plastic electronics”). These compounds offer new materials suitable for a variety of real world applications such as Organic Light Emitting Diodes (OLEDs) and Organic Photovoltaic Cell (OPVs). Our recent efforts has been focused on the synthesis of a variety of 5,6-fused ring pyridazines. These fused heterocycles will serve as synthetic models and building blocks for potential organic or organometallic conducting polymers.
Our work is focused on the synthesis of pyridazines and their organometallic rhenium complexes and polymer research. Several aryl-substituted 5,6-fused ring pyridazines have been synthesized and characterized. A pyridazyl complexe of rhenium was synthesized in three steps beginning with a 5,6-fused pyridazine. Off-metal synthesis and characterization of [Re(CO)3{1,2-C5H3(CC6H5N)(CC6H5N)}] and some aryl-substituted pyridazines (1,2-C5H3(CRNH)(CRN); R = C6H5, C4H3S, C8H5S) are reported herein.
