“…The synthesis of conjugated polymer via the cyclopolymerization of dipropargyl monomers has been very interesting method for the introduction of conjugated system in the polymer main chain via an alternating intramolecularintermolecular chain propagation [16,17]. 1,6-Heptadiyne itself had been polymerized by various initiator systems to give poly(1,6-heptadiyne) with a polyene cyclic structure [17].…”

“…1,6-Heptadiyne itself had been polymerized by various initiator systems to give poly(1,6-heptadiyne) with a polyene cyclic structure [17]. However, the resulting poly(1,6-heptadiyne) was insoluble in any organic solvent and unstable to air oxidation as like with that of polyacetylene [17]. Thus it was difficult for practical applications to optoelectronic devices as an active material.…”

The electro-optical and electrochemical properties of poly(diethyl dipropargylmalonate) were measured and discussed. Poly(diethyl dipropargylmalonate) prepared by (NBD)PdCl 2 catalyst was used for study. The chemical structure of poly(diethyl dipropargylmalonate) was characterized by such instrumental methods as NMR ( 1 H-, 13 C-), IR, and UV-visible spectroscopies to have the conjugated cyclopolymer backbone system. The microstructure analysis of polymer revealed that this polymer have the six-membered ring moieties majorly. The photoluminescence peak of polymer was observed at 543 nm, which is corresponded to the photon energy of 2.51 eV. The cyclovoltamograms of the polymer exhibited the irreversible electrochemical behaviors between the doping and undoping peaks. It was found that the kinetics of the redox process of this conjugated cyclopolymer might be controlled by the diffusion-control process from the experiment of the oxidation current density of polymer versus the scan rate.

“…25 Introduction of functional substituent to the methylene carbon at the 4-position of 1,6-heptadiyne solved the predescribed problems of poly (1,6-heptadiyne) and expanded the research areas of π-conjugated polymers. The polymerizations of various 1,6-heptadiynes having substituents had been carried out by Mo-and W-based catalysts.…”

A conjugated spirocyclic polymer was synthesized via the cyclopolymerization of 1,1-dipropargyl-1-silacyclohexane with various transition metal catalysts. The monomer, 1,1-dipropargyl-1-silacyclohexane was synthesized by Grignard reaction of 1,1-dichloro-1-silacyclohexane with propargyl magnesium bromide. This polymerization proceeded well to give the corresponding poly(1,1-dipropargyl-1-silacyclohexane). The catalytic activity of WCl 6 was found to be similar with that of MoCl 5 . The structure of polymer having the conjugated backbone with silacyclohexane moieties was characterized by such instrumental methods as NMR ( 1 H-, 13 C-), IR, and UV-visible spectroscopies. The resulting polymers were mostly yellow or light-brown powders, depending on the catalyst systems used. This polymer was completely soluble in halogenated and aromatic hydrocarbons such as chloroform, 1,2-dichloromethane, benzene, toluene, and chlorobenzene, etc. The thermal and oxidative stabilities of polymer were also studied and discussed.

“…This reaction has thus been the focus of intense research endeavors for the past 30 years 8 and is now well known to be catalyzed effectively by various transition metal complexes such as the classical Ziegler-Natta catalysts, 9,10 MoCl 5 , WCl 6 , and PdCl 2 . 11 Schrock's group 12 recently discovered that this same polymerization can be performed in a living manner by employing the well-defined Mo-alkylidene complexes of the type Mo(CH-t-Bu)(NAr)(OR F6 ) 2 [Ar ϭ 2,6-diisopropylphenyl; OR F6 ϭ OCMe(CF 3 ) 2 ].…”
