Stretchable and Self-Healable Poly(styrene-co-acrylonitrile) Elastomer with Metal–Ligand Coordination Complexes

Alkali metal salts of terephthalic acid are common reagents in the preparation of metal–ligand coordination complexes containing terephthalate anions. In the title compound, sodium hydrogen terephthalate, [Na(C8H5O4)] n , the cations occupy crystallographic inversion centres, and each bridging anion coordinates to six octahedral cations and vice versa. As seen in the known potassium derivative [Kaduk (2000). Acta Cryst. B56, 474–485; Miyakubo, Takeda & Nakamura (1994). Bull. Chem. Soc. Jpn, 67, 2301–2303], sodium hydrogen terephthalate contains short O—H...O hydrogen bonds between anions [O...O = 2.4734 (17) Å]. The structure is centrosymmetric and exhibits disorder of the H-atom position in the hydrogen bond and of the non-bridging ring C atoms in the terephthalate ion.

The oxides of nitrogen (chiefly NO, NO3−, NO2− and N2O) are key components of the natural nitrogen cycle and are intermediates in a range of processes of enormous biological, environmental and industrial importance. In this Tutorial Review, we will examine catalysts for the inter-conversions of the various nitrogen oxides that are based on metal–ligand coordination complexes, looking in particular at more recent examples that take inspiration from the natural systems.

A series of porphyrin triads (1–6), based on the reaction of trans-dihydroxo-[5,15-bis(3-pyridyl)-10,20-bis(phenyl)porphyrinato]tin(IV) (SnP) with six different phenoxy Zn(II)-porphyrins (ZnLn), was synthesized. The cooperative metal–ligand coordination of 3-pyridyl nitrogens in the SnP with the phenoxy Zn(II)-porphyrins, followed by the self-assembly process, leads to the formation of nanostructures. The red-shifts and remarkable broadening of the absorption bands in the UV–vis spectra for the triads in CHCl3 indicate that nanoaggregates may be produced in the self-assembly process of these triads. The emission intensities of the triads were also significantly reduced due to the aggregation. Microscopic analyses of the nanostructures of the triads reveal differences due to the different substituents on the axial Zn(II)-porphyrin moieties. All these nanomaterials exhibited efficient photocatalytic performances in the degradation of rhodamine B (RhB) dye under visible light irradiation, and the degradation efficiencies of RhB in aqueous solution were observed to be 72~95% within 4 h. In addition, the efficiency of the catalyst was not impaired, showing excellent recyclability even after being applied for the degradation of RhB in up to five cycles.
