Sulfur-containing species (SCS), especially sulfur dioxide-relevant species play an essential role in ecological balance. Owing to intrinsically labile and mobile characteristics of SCS, it is still considered to be an insurmountable challenge for multiplexed tracking dynamics SCS with distinct molecular structure, valence state and condensed state. To address this key problem, we proposed herein an alternative way of versatile single-molecule sensors (VSMs) by intramo-lecularly integrating high affinity target-guided multiple recognition units into a single sensory molecule, clarified as molecular Nezha available in triplexed responses to gaseous sulfur dioxide, liquid sulfur trioxide and aqueous bisulfite through ubiquitous charge-transfer and nucleophilic addition. High-performance molecular Nezha remarkably facilitated for promising applications in a quantitative visualization of SCS on Lab-on-paper, tracking dynamics transformation of SCS as well comprehensive evaluating multiphase adsorption science of SCS on an advanced Zeolitic imidazolate framework-8 (ZIF-8).
