Au(I)-SRs [R = -(CH2)nH, n = 2~10, 12, 14, 16, and 18] were synthesized by mixing gold salt, HAuCl4, and n-alkanethiols in tetrahydrofuran. The Au(I)-SRs showed a highly ordered layer structure and the ordering increased as the length of the alkyl chain increased. These materials emitted bright orange-red light (λem ~ 610 nm) that was visible to the naked eye upon the irradiation with UV light. The intensity of the emitted light increased as the length of the alkyl chain in the thiolates increased. We believe that the luminescent properties of the complexes are highly related to the coordination of gold atoms in the backbone region, which is facilitated by the layered structure of the Au(I)-SRs. |
