“…1430 cm −1 can be assigned to the δ (CH 2 ) deformation mode. Compared with 2 a – c , the asymmetric ν (CH 2 ) stretching and δ (CH 2 ) deformation vibrations are shifted slightly to higher frequencies ( 2 a – c , 2903/2853 and 1434 cm −1 ) [63] . The C−N unit of the Py ligands gives rise to bands at 1594 and 1572 cm −1 ( 3 a ), 1595 and 1579 cm −1 ( 3 b ), as well as 1605 cm −1 ( 3 c ) ( ν (C=N)), and at 1260 cm −1 ( 3 a ), 1229 cm −1 ( 3 b ) and 1220 cm −1 ( 3 c ) ( ν (C−N)).…”

The synthesis and twin polymerization (TP) of Si(OCH2py)4 (3 a, py=2‐cC5H4N; 3 b, py=3‐cC5H4N; 3 c, py=4‐cC5H4N) is discussed. The solid state structures of 3 b, c were confirmed by single‐crystal X‐ray crystallography showing non‐conventional H‐bonding, forming 2D chains (3 b) or 3D networks (3 c). Thermally induced TP of 3 a–c and their simultaneous polymerization with 2,2‘‐spiro‐bi[4H‐1,3,2‐benzodioxasiline] (4) is described. The resulting hybrid materials were characterized by 1H, 13C{1H}, and 29Si{1H} CP MAS NMR spectroscopy confirming the transformation of the SiOCH2 moieties into CH2 groups enabling the formation of the respective polymers. These results were supported by HAADF‐STEM studies, displaying micro‐structuring. Nitrogen‐containing porous carbon materials C_1–C_3 show surface areas of 1300 and 1700 m2 g−1, large pore volumes between 0.6–1.2 cm3 g−1, and nitrogen contents of up to 3.1 at‐%. X‐ray photoemission spectroscopy reveal that pyrrolic, pyridine, and pyridone nitrogen atoms are present. If equimolar amounts of 3 a–c and 4 are simultaneously polymerized in the presence of [Pd(OAc)2] (5), then the Pd nanoparticle‐decorated material Pd@C_3 (900 m2 g−1) was obtained, which showed k values of −0.083 and −0.066 min−1 in the reduction of methylene blue and methyl orange, proving the accessibility of the Pd NPs.

“…In this regard, the characterization of IR-786 in the absence and presence of individual anions and both anions were carried out by FT-IR ( Figure 6 ) and NMR spectroscopy (data presented in the Materials and Methods section). The FT-IR spectrum of solid IR-786 has characteristic peaks for aromatic groups between 2800 and 2980 cm −1 and lacks two important bands (–CN: 2200 cm −1 and OH: 3224 cm −1 ) due to the absence of these groups in the molecule [ 26 , 27 ]. A strong peak for –CN at 2200 cm −1 appeared when IR-786 is dissolved in MeCN and CN − is added and the aromatic peaks at 2800–2990 cm −1 became stronger due to the conversion of aromatic rings to aliphatic groups.…”

The application of IR 786 perchlorate (IR-786) as a selective optical sensor for cyanide anion in both organic solution (acetonitrile (MeCN), 100%) and solvent-free solid surfaces was demonstrated. In MeCN, IR-786 was selective to two anions in the following order: CN− > OH−. A significant change in the characteristic dark green color of IR-786 in MeCN to yellow was observed as a result of nucleophilic addition of CN− to the fluorophore, i.e., formation of IR 786-(CN), which was also verified by a blue shift in the 775 nm absorbance peak to 430 nm. A distinct green fluorescence emission from the IR-786-(CN) in MeCN was also observed, which demonstrated the selectivity of IR-786 towards CN− in MeCN. Fluorescence emission studies of IR-786 showed that the lower detection limit and the sensitivity of IR-786 for CN− in MeCN was 0.5 μM and 0.5 to 8 μM, respectively. The potential use of IR-786 as a solvent-free solid state sensor for the selective sensing and monitoring of CN− in the environment was also demonstrated. On solvent-free solid state surfaces, the sensitivity of the IR-786 to CN− in water samples was in the range of 50–300 μM with minimal interference by OH−.
