Abstract

Abstract A set of red-light-excited, metal-free room-temperature phosphorescence (RTP) systems were constructed by 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 as is known. The RTP emission can be switched ON-OFF by adding acid and alkali alternatively. A logic operation with half-subtractor function and dual-channel response (visible light emission/NIR RTP emission) was also constructed based on these properties mentioned above.
