Abstract:

Novel multinuclear metallodithiolene complexes [(Cbz)2-BTT-Pd(dppf)]2Ni[6b, Cbz=carbazole, BTT=benzene-1,2,4,5-tetrathiotate, dppf=1,1'-bis(diphenylphosphino) ferrocene] and polymer [(Cbz)2-BTT-Ni]n·[(Et)3(PhCH2)N]x(7b) with the carbazole pendent groups were synthesized and characterized. The thin films of crosslinked polymers P6b and P7b were prepared by electrochemical polymerization of compounds 6b and 7b, respectively. These films show intense and broad absorption in the near- and mid-infrared spectral regions(P6b: 1000-1600 nm, λmax=1297 nm; P7b: 800 nm-8 μm, λmax=3.9 μm) and are potentially useful as infrared optical materials.

Key words: Metallodithiolene, Carbazole, Electrochemical polymerization, Infrared absorption
