摘 要

合成两个新型的、末端具有氨基的4,6-二苯基-2,2’-联吡啶铂芳基炔配合物（1和2），在进行核磁和红外结构表征的基础上，通过紫外-可见吸收光谱、发射光谱系统地研究他们的发光性质。配合物在紫外区展现了强的、宽的无精细结构的¹π-π*吸收，同时发现当炔配体为供电子基的芴时，供电子基的芴配体的吸收相对于吸电子的萘酰亚胺配体呈现了一定的红移。由于金属到配体间的电荷转移（³MLCT）以及配体到配体间电荷转移（³LLCT）导致这两个配合物在溶液中的发射波长位于橘黄光部分。这两个配合物在500nm以后有弱的吸收是一种潜在的非线性吸收材料，末端氨基的引入有利于后续的器件化的应用。

The synthesis and luminescence properties of 4, 6 - diphenyl - 2, 2 '- bipyridyl platinum ary acetylide alkyne complexes

Abstract

Two new 4, 6 - diphenyl - 2, 2 '- bipyridyl platinum ary acetylide alkyne complexes (1 and 2) with amino group at the end were synthesized. Their structure was confirmed by ¹ H NMR and FT-IR. Their photophysical properties were investigated systematically by ultraviolet-visible absorption spectrum, emission spectrum. All complexes exhibit strong ¹π,π*absorption bands in the UV region; and broad, structureless charge-transfer band(s) in the visible region, which red-shift when the electron-donating group was introduced into the phenylacetylide ligand than electron withdrawing group. All complexes are emissive in solution at room temperature. When excited at the charge-transfer absorption band, the complexes exhibit orange emission, which is attributed to a triplet metal-to-ligand charge transfer/intraligand charge transfer emission (³MLCT/³ILCT). The two complexes are a kind of potential nonlinear absorption material due to certain absorption at 500nm . Introduction amino to complexes is good to subsequent application of the device.
