A set of red-light-excited, metal-free room-temperature phosphorescence (RTP) systems was constructed with brominated phenolsulfonephthaleine derivatives. The best metal-free RTP system has the reddest near-infrared (NIR) RTP emission (λ = 819 nm) with the highest phosphorescence quantum yield (Φ = 3.0%) so far identified. The RTP emission can be switched ON-OFF by adding acid and alkali alternately. A logic operation with half-subtractor function and dual-channel response (visible light emission/NIR RTP emission) was also constructed based on these properties.
利用溴化酚磺酞衍生物构建了一组红光激发的无金属室温磷光（RTP）体系。目前已鉴定出的最佳无金属RTP体系具有最红的近红外（NIR）RTP发射（λ = 819 nm）以及最高的磷光量子产率（Φ = 3.0%）。通过交替添加酸和碱，RTP发射可以实现开启-关闭。基于这些特性，还构建了具有半减法器功能和双通道响应（可见光发射/近红外RTP发射）的逻辑运算。
