The oxidative addition of aryl-halogen bonds of Schiff bases (2-ClC6H4CH=N-CH2-)(2) (1), (2-BrC6H4CH=N-CH2-)(2) (2), 1,4-(2-BrC6H4CH=N-)(2)C6H4 (3), 4,4'-(2-BrC6H4CH=N-C6H4)(2) (4) and the azine (2-BrC6H4CH=N-)(2) (5) to Pd(dba)(2) has been carried out in benzene. Insoluble halogeno-bridged polymeric complexes [Pd(C6H4CH=N-CH2-)Cl}(n)] (1a), [Pd(C6H4CH=N-CH2-) Br}(n)] (2a), [1,4-BrPd (C6H4CH=N-C6H4-N=CHC6H4)PdBr}(n)] (3a), [4,4'-Pd(C6H4CH=N-C6H4)Br}(n)] (4a) and [Pd(C6H4CH=N-)Br}(n)] (5a) were formed. The bridge-splitting reactions of halogeno-bridged complexes were studied with different ligands like triphenylphosphine, triethylphosphite, 4-picoline, diethyldithiocarbamate and N-(2-hydroxy) benzylideneamine. All the double cyclopalladated complexes obtained were analysed by means of H-1 NMR and C-13 NMR spectroscopy.

New ferrocenyl-containing organic hole-transporting materials for perovskite solar cells in regular (n-i-p) and inverted (p-i-n) architectures
better solubility than JW6. The regular mesoporous TiO2-based perovskitesolarcells (n-i-p) and the inverted planar heterojunction perovskitesolarcells (p-i-n) fabricated using JW7 show the highest power conversion efficiency of 9.36% and 11.43% under 100 mW cm−2 AM1.5G solar illumination. For p-i-n cells, the standard HTM PEDOT-based cell reaches an efficiency of 12.86% under the same conditions.
