“…Plasma‐enhanced chemical vapor deposition (PECVD) is an attractive technique to fabricate a thin polymer film for photonic devices because this dry process is consistent with conventional semiconductor processes [1]. However, the applications of the technique have been limited to fields except electronic and photonic devices.…”

An important issue in the polymerization of a polymer film by plasma-enhanced chemical vapor deposition (PECVD) is how to control the polymer structure. As is generally recognized, it is extremely difficult to control the process because it is very complex. For example, various precursors in the plasma arise from fragmentation of source monomers, which can easily change by varying the plasma conditions. High-energy electrons and ions in the plasma bombard the surface of the deposited film and affect the chemical reaction on the film. Moreover, the droplets that arise from the reactor wall by sputtering will accumulate on the film. However, if we aim to fabricate only a photonically functional polymer film, we will be able to find a solution. In this paper, we propose copolymerization from two types of monomers; one type is used as jointing materials by cracking, and the other is used as a photonic functional segment without serious deformation. This difference of action arises from a difference in the formation enthalpy. To confirm this idea, as an initial step, we copolymerized a film from a mixture of benzene (C 6 H 6 ) as the functional segment and cyclohexene (C 6 H 10 ) as the jointing material under the low radio frequency power. The deposited film consists of sp 2 bonding clusters surrounded by sp 3 bonded (alkyl) networks. We confirmed that the sp 2 bonding clusters mostly belong to phenyl, with a few belonging to olefins arising from decomposed C 6 H 6 . In addition, the amount of sp 2 bonding increases proportionally with increasing ratio of C 6 H 6 in the mixture, and the ratio of phenyl in the film becomes comparable to that of polystyrene. From these facts, we speculate that C 6 H 10 acts as the jointing material and C 6 H 6 as the functional segment. Additionally, we introduced tetrafluorocarbon (CF 4 ) to the plasma. CF 4 decomposes with a smaller energy than C 6 H 10 , and it forms mainly fluorine and CF 3 radicals. The fluorine radical pulls out hydrogen from the film and reacts to form dangling bonds in the film. Moreover, we speculate that they will terminate the dangling bonds.

“…Recently, we employed the metal-free AACP of propiolates and azide to prepare Fc-containing poly(aroxycarbonyltriazole)s (PACTs) [74]. As shown in Scheme 14, heating of the mixture of propiolates (12) and 1,1 0 -bis(azidomethyl)ferrocene (13) in DMF at 80°C for 24 h readily produced PACTs (P32) with molecular weights up to 13 400 g mol -1 and fraction of 1,4-isomer higher than 87.7 % in high yields (92.7-96.9 %). It is noteworthy that this polymerization proceeded smoothly in air without excluding oxygen and moisture.…”

Ferrocene-containing polymers (FcPs) have attracted much research interest in the last decade, due to their unique properties and enormous applications. However, it is a great synthetic challenge to prepare FcPs before the advent of click chemistry. In this review, we summarized the recent research efforts on synthesizing FcPs through click reactions, which include click modification of preformed polymers and click polymerization of ferrocene (Fc) containing monomers. Due to the containing Fc moieties, the FcPs enjoy excellent redox activity, thermal stability, electrochemical property, and magnetism. Accordingly, they are promising to be used as electro-

Poly(azine ferrocene‐triazole‐xanthone amide) (PAFTXA) was successfully synthesized from azine ferrocene bisacetylene (AFcB) and 2,7‐(N‐2‐azidoacetamide) xanthone (NAzX) by using click chemistry protocol. In this paper, innovative AFcB moiety incorporated in this procedure as a monomer. This monomer was prepared in three steps from ferrocene scaffold, and the synthetic processes were discussed in details. Characterization of the synthesized novel intermediate materials, monomer, and the resulting polymer was performed by nuclear magnetic resonance, Fourier transform infrared, thermal gravimetric analysis, differential scanning calorimetry, and ultraviolet‐visible spectrophotometer. In addition, the in vitro antibacterial activity of the polymer was appraised against Gram‐positive and Gram‐negative bacteria by using minimum inhibitory concentration method. Moreover; antitumoral effects of synthesized polymer were evaluated on Hela, MCF‐7, and Saos cancer cell lines and compared with normal fibroblast cell line by means of 3‐(4,5‐dimethylthiazol‐2‐yl)‐2,5‐diphenyltetrazolium bromide assay. Promising antiproliferative effects were detected on both epitheloid and mesenchymal cancer cell lines depending on PAFTXA concentration and time. Survey on its characteristic features revealed the proficiencies of our prepared biomaterial such as its high thermal stability as well as valuable antitumoral and antibacterial capabilities that make it an appreciable candidate for further bioapplications.
