Beschreibungen/Notizen

• A donor-acceptor coordination polymer ( TPA-Zn ) was synthesized by Zn( ii )-assisted self-assembly of an in situ generated triphenylamine (TPA) cored tristerpyridine ligand. The polymer absorbs a broad-spectrum of light and exhibits visible light-assisted hydrogen generation (27.1 mmol g −1 over 9 h) from water with 2.9% quantum efficiency at 400 nm. The microscopy images show a mesoscale fibrous morphology and the Brunauer-Emmett-Teller (BET) analysis reveals the porous nature of TPA-Zn (surface area: 234.5 m 2 g; d = 6.98 nm), both of which are helpful for substrate diffusion during catalysis. A donor-acceptor coordination polymer ( TPA-Zn ) was synthesized by Zn( ii )-assisted self-assembly of an in situ generated triphenylamine (TPA) cored tristerpyridine ligand.
