Synthesis, characterization, and theoretical studies of the photovoltaic properties of novel reactive azonitrobenzaldehyde derivatives.

All dyes conduct but at different degrees of absorption; it is interesting to study the degree of conductivity and absorptivity of novel reactive azo-dyes in respect to dye-sensitized solar cells (DSSCs) to ascertain their viability for such applications. In this study, four novel reactive azo-dyes were experimentally synthesized from -aminobenzaldehyde, 4-amino-3-nitrobenzaldehyde, and aniline through series of condensation and coupling reactions. The various functional groups, molecular connectivities, and molecular weight of the various fragments of the synthesized dyes were elucidated using the GC-MS, FT-IR, UV-vis, and NMR respectively.

Di-mu-acetato-bis[(2-acetylpyridine thiosemicarbazonato)zinc(II)].

The title compound, [Zn2(C2H3O2)2(C8H9N4S)2], is a centrosymmetric dinuclear molecule with two acetate bridging ligands in a syn-syn arrangement. The Zn(II) atom is five-coordinated in a trigonal-bipyramidal configuration by three thiosemicarbazone atoms (two N and one S) and by an O atom from each of the two acetate groups.
