Twin monomers [Mg(2‐OCH2‐cC6H4O)][L]0.8 (2, L=diglyme) and [Mg(2‐OCH2‐cC6H4O)][L]0.66 (3, L=tmeda) form by their thermal polymerization interpenetrating organic‐inorganic hybrid materials in a straightforward manner. Carbonization (Ar) followed by calcination gave porous MgO (2: surface area 200 m2 g−1, 3: 400 m2 g−1), which showed in catalytic studies towards Meerwein‐Ponndorf‐Verley reductions excellent yields and complete conversions for cyclohexanone and benzaldehyde. However, with crotonaldehyde a mixture of C4–C8 compounds was obtained. When MgO was exposed to air then primarily crotyl alcohol was formed. The range of applications could be easily extended by twin polymerization of 3 in presence of [Cu(O2CCH2O(CH2CH2O)2Me)2] (4) or [Ag(O2CCH2‐cC4H3S)(PPh3)] (5), resulting in the formation of nanoparticle‐decorated porous CuO@MgO or Ag@MgO materials, which showed high catalytic reactivity towards the reduction of methylene blue.

The authors propose an on-chip microfluidic flow chemistry for non-covalent functionalization of single-walled carbon nanotubes (SWCNTs) as channel material in nanoelectronic carbon-nanotube field-effect transistors (CNT-FETs) specifically aiming for personalized optoplasmonic sensor solutions. Applying pyrene alkanethiol derivatives, dissolved in chloroform, and a dispersion of gold nanoparticles in triglyme, the authors conduct the proof-of-principle to fabricate arrays of photosensitive CNT-FETs using flow chemistry on wafercompatible hardware. The spectral photoresponse of the obtained sensor devices appears clear and reproducible and can be related to the surface plasmon polaritons of the gold nanoparticles. The sensor devices yield photometric responsivities of R A % 8 Â 10 À3 AW À1 and response times of t 0 % 9 s. The results extend a previously reported approach for covalent functionalization (Blaudeck et al., Microelectron. Eng. 2015, 137, 135) and show the potential of flow chemistry combined with wafer-level microfabrication for selectively functionalized nanostructured sensor arrays.
