Preparation of head-to-tail φ-conjugated poly(thiophenepyridine) and polypyrimidine by organometallic polycondensation
The metalation of BrThPyBr (Th: thiophene-2,5-diyl; Py: pyridine-2,5-diyl) and 2-iodo-5-bromopyrimidine with i-PrMgCl proceeds regioselectively. The cross-coupling polycondensation of regioselectively metalated intermediates gives head-to-tail φ-conjugated poly(thiophenepyridine) and polypyrimidine, respectively, and their packing structures in the solid state and optical data are discussed.
Columnar mesophases from half-discoid platinum cyclometalated metallomesogens
A series of liquid crystals have been synthesized and studied based upon mononuclear ortho-platinated rod-like heteroaromatic and 1,3-diketonate ligands. The liquid crystalline properties of these molecules were investigated using polarized light optical

Mixed Heteroarene Oligomers
Various types of mixed heteroarene oligomers can be readily prepared from heteroarene dihalides via stepwise coupling with heteroaryl Grignard reagents catalysed by a palladium-phosphine complex.
