摘要：
A series of thermally stable organic polymers [poly(2,5-diethynylpyridine] (5), [poly(1,4- diethynyl benzene)] (6), [poly(2,5-dialkyl-p-phenyleneethynylene)] (7), and [poly(p,p-diethynylbiphenyl)] (8), were synthesized by the reaction between diterminal aryleneethynylene, [HCCArCCH] {Ar= C₅H₅N ( 1) ; Ar = C₆H₆ (2) ; Ar =C₆H₄(CH₃)₂ (3) ; Ar = C₆H₄-C₆H₄ (4) } and CuCl in pyridine by Hay’s oxidative coupling method. Then the organometallic polymers [PhPt(PⁿBu₃)₂-C≡C-(Ar-C≡C)_n-Pt(PⁿBu₃)₂Ph] {Ar = C₅H₅N (9) ; Ar = C₆H₆ (10) ; Ar = C₆H₄(CH₃)₂ (11) ; Ar = C₆H₄-C₆H₄( 12) } were synthesized by the reaction of organic polymers 5, 6, 7 and 8 with metal precursor (PⁿBu₃)₂ PtPhCl in diethylisopropileamine with good yield. These metal-linked polymers were characterized by IR, ¹H-NMR, ¹³C-NMR and ³¹P-NMR spectra. Finally the molecular weight of the organometallic polymers ( 9, 10, 11 and 12) was determined by gel permeation chromatography (GPC). It is clearly observed from GPC that the polymers were synthesized with different degree of polymerization.

Keywords : Organometallic polymers; Hay’s Oxidative coupling. GPC.
