Synthesis of Novel Soluble Dithiolene Complex as Photosensitizer
Three metal-bis(dithiolene) complexes CNi, CPt, CPd with strong and broad absorption in the near-infrared (NIR) region are synthesized as photosensitizers, in which carbazole is used as strong electrondonating group at the molecular periphery.Their chemical structures are characterized in detail by 1H-NMR, 13C-NMR, IR and XPS spectra.The thermal, electrochemical and optical absorption properties are systematically investigated and discussed.They all have good solubility in organic common solvents due to the introduction of2-ethylhexanyl aliphatic chains into the complexes.The UV-vis-NIR spectra reveal that they show strong and broad absorption in the NIR region of 800～1550nm owing to the optimization of electron-donating groups in the molecular periphery.The thermogravimetric measurement indicates that their thermal decomposition temperature is all above 350 ℃, exhibiting good thermal stability.Their electrochemical band gap is narrow through the calculation from the data of cyclic voltammetry.The low band gap further implies the potential improvement of NIR absorption performance.
