Mono- and Diplatinum Polyynediyl Complexes as Potential Push–Pull Chromophores: Synthesis, Characterization, TD-DFT Modeling, and Photophysical and NLO Properties
presents the syntheses and photophysical and the electrochemical characterizations of four new mono- and diplatinum polyynediyl complex chromophores end-capped with diphenylpyranylidene and pentafluorophenyl moieties. The nonlinear optical properties (NLO) of these compounds are investigated using the electric-field-induced second harmonic generation (EFISH) technique, and their experimental optical properties

The present work describes the one-pot synthesis and electrochemical, photophysical and second-ordernonlinear optical (NLO) properties of a series of dipolar π-delocalized Ru(II) dialkynyl complexes. The eight new asymmetrical D–π-Ru–π-A push–pull chromophores incorporate pyranylidene ligands as pro-aromatic donor groups (D) and formaldehyde, indane-1,3-dione, pyrimidine or pyrimidinium as electron-attracting

unsymmetrical push–pull diacetylide platinum-based complexes. These D–π-Pt–π-A complexes incorporate pyranylidene ligands as pro-aromatic donor groups (D), diazine rings as electron-withdrawing groups (A), and various aromatic fragments (styryl or thienylvinyl) as π-linkers separating the platinum diacetylide unit from the donor and the acceptor groups. This is one of the first examples of push–pull chromophores
