A chiral polymer with alternating conjugated segments and (1R,2R)-1,2-diaminocyclohexane as a unit with C2 symmetry

A chiral conjugated polymer was prepared via the palladium catalysed coupling reaction between 1,4-di-ynyl-2,5-dialkoxybenzene and a bis-5-bromothienyl derivative of (1R,2R)-1,2-diaminocyclohexane as a chiral unit with C2 symmetry and a unit with complexing properties. The resulting chiral polymer of which itʹs backbone consists of alternating conjugated segments and chiral complexing units, showed intense luminescence properties and was used as a ligand in the rhodium-catalysed hydride transfer reduction.
