A detailed study of how two factors (substituents on ancillary ligands and solvents during dye assembly) affect performances of copper(i) diimine dyes in DSCs with phosphonic acid anchoring groups is presented.

Azobenzenophanes are fascinating macrocycles, which are of special interest due to their unique photochromic behavior. Cyclotrisazobenzenes 2 (R = H, Br, tBu) were prepared to probe how much strain the photoisomerization of the azobenzene motive can tolerate. The macrocycles were synthesized in an overall yield of 10-20 % from ortho-phenylenediamine

LECs incorporating [Ir(ppy)2(Naphbpy)][PF6] (Hppy = 2-phenylpyridine, Naphbpy = 6-(2-naphthyl)-2,2′-bipyridine) in the emissive layer show high luminance and exceptional stabilities.

Dye-sensitized solar cells have been assembled using a sequential approach: a TiO 2 surface was functionalized with an anchoring ligand, followed by metallation with Zn(OAc) 2 or ZnCl 2 , and subsequent capping with a chromophore 10 functionalized 2,2':6',2"-terpyridine; the DSCs exhibit surprisingly good efficiencies confirming the effectiveness of the new strategy for zinc-based DSC fabrication.

A study of organic and zinc(ii)-containing DSC sensitizers with second-generation diphenylamino-dendrons and benzothiadiazole domains shows that the organic dye has a superior performance.
