Conjugated Platinum-Poly-Ynes with extended Arylene Ethynylenes

The platinum-poly-yne polymers poly[ trans -bis(tri-n-butylphosphine) platinum-poly (4,4´- diethynylenearylene)] (arylene = biphenylene 3 and anthracene 4) were synthesized by the condensation reaction between poly(diethynylenearylene) (arylene = biphenylene 1 and anthracene 2 ) and trans -[(P n Bu 3 ) 2 PtCl 2 ] in diisopropyl amine and dichloromethane under nitrogen atmosphere in the presence of CuI catalyst. The newly synthesized platinum containing poly-yne polymers exhibit good solubility in common organic solvents. These metal linked polymers were characterized by IR, 1 H NMR and 31 P NMR spectroscopy. Journal of Bangladesh Academy of Sciences, Vol. 39, No. 2, 195-202, 2015
