The insertion of carboxysalen-type complexes into magnetic layered transition-metal simple hydroxides has provided new hybrid compounds. Three kinds of carboxysalen ligands have been used: an ethylenediamine bridge (SED-H2), a chiral cyclohexan

A new Zn(II)/Eu(III) compound with the N,N′-ethylenebis(5-carboxysalicylideneamino) ligand (H4Salendc) has been synthesised and its photophysical behaviour studied. This species, [Zn(Salendc)Eu(CH3COO)(DMSO)]·xH2O·0.5CH3CN (x = 3.5–4), has been characterised by XRD, XEDS and SEM and HTEM microscopies. Experimental results suggest the formation of a one-dimensional polymeric compound. The compound behaves as a luminescent material in the solid state. Moreover, it exhibits acidochromic properties upon the addition of a few drops of HCl and in the presence of its vapours. The emission intensity of the bands attributed to the Eu(III) ion can be also modulated by the temperature and by the presence of water, so that this species is a good candidate for its use as a luminescent acid, temperature and water sensor.

Photocatalytic production of hydrogen by water splitting is a promising pathway for the conversion of solar energy into chemical energy. However, the photocatalytic conversion efficiency is often limited by the sluggish transfer of the photogenerated charge carriers, charge recombination, and subsequent slow catalytic reactions. Herein, we report a highly active noble-metal-free photocatalytic system for hydrogen production in water. The system contains a water-soluble nickel complex as a molecular cocatalyst and zinc sulfide on 1D cadmium sulfide as the heterojunction photocatalyst. The complex can efficiently transport photogenerated electrons and holes over a heterojunction photocatalyst to hamper charge recombination, leading to highly improved catalytic efficiency and durability of a heterojunction photocatalyst– molecular cocatalyst system. The results show that under optimal conditions, the average apparent quantum yield was approximately 58.3 % after 7 h of irradiation with monochromatic 420 nm light. In contrast, the value is only 16.8 % if the molecular cocatalyst is absent. Such a remarkable performance in a molecular cocatalyst-based photocatalytic system without any noble metal loading has, to the best of our knowledge, not been reported to date.
