“…[22,71] In both cases, the EGDA crosslinker was used to achieve copolymerization. While linear homopolymer poly(VP) dissolves in water, a poly(VP-co-EGDA) film with a low crosslink density was stable in water, having a water/air contact angle of just 118.…”

The techniques of initiated chemical vapor deposition (iCVD) and oxidative chemical vapor deposition (oCVD) enable the fabrication of chemically well‐defined thin polymeric films on complex objects with micro‐ and nano‐scale features. By depositing polymers from the vapor phase, many wetting and solution effects are avoided, and conformal films can be created. In iCVD, a variant of hot filament CVD, the deposition rate is enhanced and chemical functionalities of the polymers' constituents are maintained by including a thermally labile initiator in the feed stream. Due to the low energy required when using an initiator, delicate substrates can be coated. In oCVD, infusible, electrically conductive films are formed directly on the substrate of interest as the oxidant and monomer are introduced into the reactor simultaneously. This Feature Article provides an overview of the work that has been done to develop iCVD and oCVD into platform technologies. Relevant background, fundamentals, and applications will be discussed.

“…The band at 1649 cm À1 in the FTIR spectrum ( Figure 3) is considered to arise from the C=O stretching mode of the PVP molecule, [22] which indicates the presence of the PVP capping agent in the AuNCs. Figure 4 shows the XPS spectra of the prepared AuNCs.…”

A series of hybrid phosphine-phosphoramidite ligands has been designed and synthesized in moderate yields from chiral BINOL (1,1'-bi-2-naphthol) or NOBIN (2-amino-2'-hydroxy-1,1'-binaphthyl). They have achieved highly regio- and enantioselectivities in Rh-catalyzed asymmetric hydroformylations of styrene derivatives (branched/linear ratio up to 56.6, ee up to 99 %), vinyl acetate derivatives (up to 98 % ee), and allyl cyanide (up to 96 % ee). Systematic variation of ligand structure showed that the steric factor on the phsophoramidite moiety determined the performance of the ligand. With the increased hindrance, the branched/linear ratio rose, while the ee value dropped in the hydroformylation of styrene. However, the N-substituents did not influence the selectivities much.

“…EGDA is a cross-linker that has been employed repeatedly in iCVD polymerization to enhance the mechanical properties of the film [67,68]. p(PFDA-co-EGDA) was deposited in channels of poly(dimethylsiloxane) (PDMS) microfluidic devices as a barrier coating to prevent diffusion and swelling [50] or to provide an adequate interface for the synthesis of nanoparticles in droplet-flow microfluidic reactors [52].…”
