Hyperpolarization is one of the methods for NMR signal enhancement . NMR sensitivity can be further enhanced by combining hyperpolarization with chemical exchange saturation transfer (CEST), which termed “Hyper‐CEST”. A H 2 S sensor is reported that contains a cryptophane group for NMR sensing and a naphthalimide group for fluorescence sensing, together with an azide group as the reaction site. Upon reacting with H 2 S, the fluorescence and 129 Xe NMR signal changes, which may provide a universal template for converting a fluorescence sensor into an 129 Xe Hyper‐CEST MRI sensor. More information can be found in the Communication by X. Zhou, M. Liu, et al. on page 7648.
