alkoxide side chain) that stem from the central phenylene moiety. The X-ray crystal structures of two of the prepared complexes are reported: one corresponds to a shorter rod, 1,4-bis[trans-(PEt3)2ClPd-CC]-2,5-diethoxybenzene (6c), while the second one is associated with a longer rod, the binuclear complex 1,4-bis[trans-(PEt3)2ClPd-4-(–CC–C6H4–CC)]-2,5-diethoxybenzene (7c). All new compounds were characterized
已经开发了一种罕见的六种离散的双核[PdCl(PEt 3)2 ]亚苯基亚乙炔基棒,它们带有烷氧基侧链(甲氧基,乙氧基和庚氧基),并且已经给出并讨论了它们的固态光致发光结果。较短的桥接配体是通式H-C C-C 6 H ^ 2(R)2 -C C-H,其中R = H,OCH 3,OC 2 H ^ 5,和OC 7 ħ 15,而长一个基于H–C C–C 6 H 4 –C C–C 6 H 2(R)2–C C–C 6 H 4 –C C–H,其中R = OCH 3,OC 2 H 5。这些配体在主要尺寸(主链长度)以及源自中心亚苯基部分的侧链(R,醇盐侧链)中的碳数均显示出增加的长度。报告了两种制备的配合物的X射线晶体结构:一种对应于较短的棒,即1,4-双[反式((PEt 3)2 ClPd-C C] -2,5-二乙氧基苯(6c),而第二个与更长的杆相关联,则是双核复合物1,4-bis [反式-(PEt 3)2ClPd-4-(–
