A hydrogen bond cross-linked luminescent supramolecular network polymer and its application for the detection of alkyl iodides with differentiation capabilities from aromatic iodides

Abstract

Here, we have demonstrated a luminescent network polymer through H-bonds cross-linking strategy by connecting poly (4-vinyl pyridine) chains with perylene diimide (PDI) cross-linker. The formation of network structure through hydrogen...

A palladium nanoparticle implanted polymer membrane for reusable dip-catalysis of diverse C–C and C–heteroatom (O/S/N) coupling reactions

“…Pure P4VP exhibits characteristic transmittance peaks at 994 and 1598 cm À1 corresponding to the symmetric ring stretching absorption mode of the pyridine ring and CQN stretching vibration, respectively. 21 After making a composite with PdNPs, the peak at 994 cm À1 shifted to 1004 cm À1 with generation of a new peak at 1029 cm À1 (Fig. S3b, ESI †) clearly attributed to strong interaction between the pyridine and Pd atom through metal ligand coordination.…”

“…The detailed method for the preparation of the membrane is described in the experimental section. P4VP was first prepared by atom transfer radical polymerization 21 of 4-vinyl pyridine (4VP) in 2-propanol with PECl as the initiator and CuCl/tris[2-(dimethylamino)ethyl]amine (Me 6 -TREN) as a catalyst at 40 °C (Fig. S1, ESI†).…”
