“…The synthesis of various boron-containing polymers is due to the creation of luminescent, electroactive, sensory, thermo-, and fire-resistant materials [ 63 , 64 , 65 ]. The reaction of decaborane modification of a polymer containing –C≡CH groups and synthesized in the presence of a Ni(C 5 H 7 O 2 ) 2 /Ph 3 P complex is described [ 66 ]. However, doubts arise about the correctness of the description of the intramolecular structure of the resulting substance, since there are contradictions in the interpretation by various authors of the intramolecular structure of the initial polyaryl acetylene resin.…”

“…However, doubts arise about the correctness of the description of the intramolecular structure of the resulting substance, since there are contradictions in the interpretation by various authors of the intramolecular structure of the initial polyaryl acetylene resin. The authors [ 66 , 67 ] believe that the poly-DEB has a mostly linear structure. On the other hand, [ 68 , 69 ] indicates the branched structure of polyDEB with the presence of even phenylene fragments in them.…”

Anionic Polymerization of Para-Diethynylbenzene: Synthesis of a Strictly Linear Polymer

et al. 2022

Anionic homo- and copolymerization of p-diethynylbenzene in the presence of n-BuLi in polar solvents was carried out. The use of hexamethylphosphortriamide (HMPA) makes it possible to synthesize a completely linear soluble polymer that does not have branching and phenylene fragments. A copolymer of p-diethynylbenzene with diphenyldiacetylene was synthesized. Homo- and copolymers of p-diethynylbenzene have high thermo- and thermo-oxidative stability. By the interaction of side reactive ethynylphenylene groups with various reagents, it is proposed to synthesize clusters along the conducting chain of poly-p-diethynylbenzene. Due to presenting C≡CH side groups, boron, copper, and cobalt derivatives were synthesized. It is shown that not all theoretically possible stereoisomers can be formed as a result of the polymerization. The application of p-diethynylbenzene polymers for the modification of industrial samples of epoxy novolac resin, oligoester acrylates, and carbon fibers has been demonstrated.

“…The authors of [23,24] admitted this possibility based on the known facts of effective cyclotrimerization of monoacetylenes in the presence of these catalysts. On the other hand, the use of Ph 3 P / Ni(acetylacetonate) 2 , according to the authors, [29,30] leads to the formation of linearly branched polyDEB without phenylene fragments.…”

In this review, all available publications on the polymerization of all isomers of bifunctional diethynylarenes due to the opening of C≡C bonds were considered and analyzed. It has been shown that with the use of polymers of diethynylbenzene, heat-resistant and ablative materials, catalysts, sorbents, humidity sensors, and other materials can be obtained. Various catalytic systems and conditions of polymer synthesis are considered. For the convenience of comparison, the publications considered are grouped according to common features, including the types of initiating systems. Critical consideration is given to the features of the intramolecular structure of the synthesized polymers since it determines the entire complex of properties of this material and subsequent materials. Branched and/or insoluble polymers are formed as a result of solid-phase and liquid-phase homopolymerization. It is shown that the synthesis of a completely linear polymer was carried out for the first time by anionic polymerization. The review considers in sufficient detail publications from hard-to-reach sources, as well as publications that required a more thorough critical examination. The review does not consider the polymerization of diethynylarenes with substituted aromatic rings because of their steric restrictions; the diethynylarenes copolymers with complex intramolecular structure; and diethynylarenes polymers obtained by oxidative polycondensation.
