Luminescent platinum(II) small molecules have aroused much attention due to their unique Pt(II)–Pt(II) interaction and intriguing luminescence properties; while incorporation of Pt(II) centers into polymers is still in its infancy. In this work, a class of random copolymers ((M1)x-co-(MPt)y; x = 200, y = 1, 2, 4) was synthesized by copolymerization of a newly designed norbornene-functionalized platinum(II) complex MPt and oligoethylene glycol modified monomer M1 using ROMP method. Compared to monomer MPt, the resulting polymers exhibit enhanced Pt(II)–Pt(II) interaction and intense low-energy emissions because of the confinement effect. Moreover, the photophysical properties of MPt and polymers ((M1)x-co-(MPt)y; x = 200, y = 1, 2, 4) were found to be highly dependent on the solvents and platinum(II) content in the polymers. Through switching on and off of the Pt(II)–Pt(II) interaction, (M1)200-co-(MPt)4 has been successfully demonstrated to be a self-referenced luminescent thermometer, which showed 2.11% K−1 (in TCE, 278K) relative temperature sensitivity, excellent reversibility and repeatability.

基于含异氰酸铂(II)的共聚物开发发光比例温度计

发光的铂(II)小分子由于其独特的Pt(II)-Pt(II)相互作用和引人入胜的发光特性而备受关注。尽管Pt(II)中心并入聚合物中仍处于起步阶段。在这项工作中,通过新设计的降冰片烯官能化铂(II)的共聚反应合成了一类无规共聚物((M 1x - co-(M Pty ; x = 200,y = 1,2,4) )使用ROMP方法将M Pt与低聚乙二醇改性的单体M 1进行复合。与单体M Pt相比,由于限制作用,所得聚合物表现出增强的Pt(II)–Pt(II)相互作用和强烈的低能发射。此外,发现M Pt和聚合物((M 1x - co-(M Pty ; x = 200,y = 1,2,4)的光物理性质高度依赖于溶剂和铂(II )在聚合物中的含量。通过铂(II)-Pt(II)的相互作用的接通和关断,(M 1200 -- (M4已被成功地证明是一个自参考发光温度计,其显示2.11%K-1(在TCE中为278K)相对温度灵敏度,出色的可逆性和可重复性
