“…In addition, the particles exhibited a yellow color, which is always observed in substituted acetylene-based polymeric particles and originates from helical substituted polyacetylene chains. [ 40,[46][47][48][49]51 ] This provides further support for our conclusion that the particles were constructed by polyphenylacetylene. For poly(1-naphthylacetylene) particles, due to the poor solubility of the corresponding polymer, we could not record NMR spectra with satisfactory resolution.…”

“…Nonetheless, the process just provided polymeric particles with large size, i.e., several hundred micrometers in diameter. In addition, the polymeric particles are limited to propargyl derivatives (propargylamides and propargylsulfamides) . To further extend the types of acetylenic‐derived polymer particles, we in the present study established an advanced suspension polymerization technique and especially excitingly, we successfully achieved the suspension polymerization of aromatic acetylene derivatives, which resulted in polymer particles even at nanoscale in size.…”

Polymeric particles are constructed by aromatic acetylene derivatives through suspension polymerization approach. Phenylacetylene and 1-naphthylacetylene are used as monomers to conduct suspension polymerization in aqueous media at room temperature by using (nbd) Rh + B -(C 6 H 5 ) 4 as catalyst and polyvinylpyrrolidone (PVP) as stabilizer. The suspension polymerizations provide polymeric particles in high yield (>80%). Scanning electron microscopic images demonstrate that the particles assumed spherical morphology. The key factors infl uencing the formation of particles are systemically investigated. Under the optimized conditions, i.e., stirring speed being 500 rpm and with PVP as stabilizer in aqueous media, the resulting polyphenylacetylene particles exhibit satisfactory regularity in spherical morphology. Fourier-transform infrared and 1 H NMR spectra confi rm the occurrence of polymerization, while UV-vis absorption spectra demonstrate the helical structures of the polymer chains constructing the particles. The polymer chains form high cis contents (>87%) according to Raman spectra. Thermogravimetric analysis shows the high thermostability of the particles. a majority of the polymeric particles created so far were derived from vinyl polymers. For acetylenic polymers, in particular aromatic acetylenic polymers, it is still a big challenge to prepare their particles.As far as acetylenic polymer-based particles are concerned, the most intriguing feature lies in the polymer chains possessing conjugated structures, largely different from the vinyl polymer counterparts. Just like other conjugated polymers, for instance, polyfl uorenes, [ 13 ] polypyrroles, [ 14 ] polycarbazoles, [ 15 ] polythiophenes, [ 16 ] and polyanilines, [ 17 ] acetylenic-based polymer particles have wide potential applications in such signifi cant areas like sensors, [18][19][20] probes, [ 21 ] bio-imaging agents, [ 22 ] and lightemitting materials. [ 23,24 ] As a typical category of conjugated polymers, substituted polyacetylenes [25][26][27][28][29][30][31][32][33][34] are particularly expected to fi nd signifi cant practical applications in diverse areas ranging from materials science [ 35 ] to medical and biological fi elds.

Electroactive ion exchange materials (EIXMs) with unique electrochemically switched ion exchange function have been extensively applied in various fields including high value-added ion recovery, toxic ion removal, energy storage device and electrochimical ion sensor. In particular, the charge and discharge of EIXMs can be electrochemically controlled by external electric field or by redox agent while the charge balance is compensated via the ion exchange with electrolyte solution. To date, the discovered EIXMs mainly involve inorganic compounds with mixed-valence transition metals, organic conducting polymers and organic-inorganic hybrid materials. Compared with their bulk forms, nanostructured EIXMs have aroused considerable research interest recently owing to their unique properties such as larger surface area, better ion diffusion path and more excellent electron transfer property. In this article, the design principles and synthetic routes for the development of various nanostructured EIXMs and their applications in the fields of selective ion separation, supercapacitors and electrochemical ion sensors are reviewed. In addition, the main challenges and future prospects for the further development of high-performance EIXMs are discussed.

“…For example, graphitic carbon, which consists of sp 2 hybridized carbon bonds, has received much attention for use in energy storage devices such as electrochemical capacitors because it possesses not only high electrical conductivity and low ion-transport resistance, but is also easier to synthesize than graphene and CNTs [8,9]. As another carbon nanomaterial, conjugated polyacetylene has also been studied as a material for electrical and optical applications due to its high electric conductivity with controlled doping [4,10]. The high potential for such materials in various industrial applications has resulted in a focus on the development of a facile method for high-yield, and selective synthesis of such carbon materials.…”

A B S T R A C TAn electrochemical deposition technique was developed to realize high yield and selective synthesis of target carbon nanomaterials. The electrochemical reduction of halogenated carbons, such as carbon tetrachloride, in an ionic liquid was found to result in the formation of a thick graphitic carbon film over a Ni substrate, whereas polyacetylene formation was confirmed in the presence of a small amount of H 2 O. Such a novel high yield, selective carbon synthesis is expected to be a promising technique for the design of various carbon nanomaterials.
