Aggregation-Induced Ignition of Near-Infrared Phosphorescence of Non-Symmetric [Pt(C^N*N'^C')] Complex in Poly(caprolactone)-based Block Copolymer Micelles: Evaluating the Alternative Design of Near-Infrared Oxygen Biosensors.

本文报道了基于两亲性聚(ε-己内酯-b-乙二醇)嵌段共聚物（PCL-b-PEG）胶束负载非对称[Pt(C^N*N'^C')]配合物（Pt1）的制备与表征。随着胶束中铂配合物含量增加，所得纳米物种出现近红外（NIR）磷光点火效应，在12 wt.% Pt1时NIR发射成为主要组分；780 nm NIR带的出现伴随量子产率提高3倍，双光子...
