Pt(dmit)(L)（dmit2−= 1,3-二硫醇-2-硫酮-4,5-二硫醇根阴离子；L = 2,2'-联吡啶、1,10-菲咯啉、4,4'-二甲基-2,2'-联吡啶、N-乙基-2-吡啶二胺和N-异丙基-2-吡啶二胺）已制备。它们在地面凝视中被极化，在 8000-14000 cm−1 区域表现出配体到配体的电荷转移吸收带。这些复合物表现为半导体，在 25 °C 时电导率为 1 × (10−9∼ 10−11) S cm−1 作为压实颗粒。将碘掺杂到配合物中后，它们被部分氧化，得到含有 I3− 和 I5− 离子的 Pt(dmit)(L)·Ix(x= 1.9 ∼ 2.3)，其电导率与相应的 Pt(dmit)(L) 配合物相比提高了 2 至 4 倍。讨论了碘掺杂配合物的红外、拉曼和 ESR 光谱。
Pt(dmit)(L) (dmit2−= the 1,3-dithiole-2-thione- 4,5-dithiolate anion; L = 2,2′-bipyridine, 1,10- phenanthroline, 4,4′-dimethyl-2,2′-bipyridine,N-ethyl- 2-picolinaldimine, andN-isopropyl-2-picolinaldimine) have been prepared. They are polarized in the ground stare, exhibiting a ligand-to-ligand charge transfer absorption band in the 8000-14000 cm−1region. These complexes behave as semi-conductors with electrical conductivities of 1 × (10−9∼ 10−11) S cm−1at 25 °C as compacted pellets. On doping iodine into the complexes, they have been partially oxidized to afford Pt(dmit)(L)·Ix(x= 1.9 ∼ 2.3) containing I3−and I5−ions, whose electrical conductivities are raised by two to four powers compared with those of corresponding Pt(dmit)(L) complexes. IR, Raman, and ESR spectra of the iodine-doped complexes are discussed.
