合成了一系列π共轭共聚物{(P)[Re]x (x = 0.1, 0.2, 0.5)}，并在骨架中与fac-(bpy)Re(I)(CO)3Cl （bpy = 2,2′-联吡啶，Re =铼）配色。Re(I)生色团的含量由(P)[bpy]x （x = 0.1, 0.2和0.5）共聚物中bpy片段的含量精确控制。采用1H核磁共振（NMR）和傅里叶变换红外（FT-IR）对(P)[Re]x共聚物的结构进行了表征，并通过电子吸收、稳态和时间分辨荧光以及场致表面光伏光谱（SPS）对其光学和电子性能进行了测量。在室温下，可以观察到表面-(bpy)Re(I)(CO)3Cl发色团的金属-配体电荷转移（1MLCT）特征吸收带和3MLCT的红色发射。使用(P)[Re]x共聚物作为活性层的电致发光（EL）器件显示出增强的红色3MLCT发射。然而，光致发光（PL）和EL e…
A series of π-conjugated co-polymers {(P)[Re]x (x = 0.1, 0.2, and 0.5)} incorporated with fac-(bpy)Re(I)(CO)3Cl (bpy = 2,2‘-bipyridine, Re = rhenium) chromophores in the backbones have been synthesized. The Re(I) chromophore contents were accurately controlled by the contents of bpy segments in (P)[bpy]x (x = 0.1, 0.2, and 0.5) co-polymers. The structures of (P)[Re]x co-polymers were characterized by 1H nuclear magnetic resonance (NMR) and Fourier transform infrared (FT-IR) analysis, and their optical and electronic properties were measured by electronic absorption, steady-state and time-resolved fluorescence, and field-induced surface photovoltaic spectroscopy (SPS). At room temperature, the characteristic metal-to-ligand charge-transfer (1MLCT) absorption band and red emission of 3MLCT from fac-(bpy)Re(I)(CO)3Cl chromophores can be observed. Electroluminescence (EL) devices that use (P)[Re]x co-polymers as the active layers showed enhanced red 3MLCT emission. However, the photoluminescence (PL) and EL e...
