摘 要：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（λp=819 nm） with the highest phosphorescence quantum yield(ΦRTP=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/NIRRTP emission） was also constructed based on these properties.
