“…Along these lines, we proposed to replace the TTF core with p-phenylene-extended TTF to lower the HOMO-LUMO gap, because the first oxidation potential is lower than for TTF [21], and to stabilize the protonated semiquinone form, which might offer a dissymmetric coordination site and thus give the possibility to reach new molecular systems. The coordination reaction between [Dy(hfac)3]·2H2O (hfac − refers to 1,1,1,5,5,5-hexafluoroacetylacetonate) and the 2,2′-benzene-1,4-diylbis(6-hydroxy-4,7-di-tert-butyl-1,3-benzodithiol-2-ylium-5-olate biradical triad [22] (L) (Scheme 1) led to the formation of the {[Dy(hfac)3(L)]·2C6H14}n (1) polymer. The X-ray structure and photophysical and magnetic properties were studied.…”
