摘要：
A dual-emission ratiometric fluorescent sensor consisting of a Tb-based metal organic framework (MOF, Tb-DOBDC) has been developed based on an excited-state proton transfer (ESPT) response linker. Due to the ESPT process, Tb-DOBDC exhibits dual emission, which affords a crucial condition for the detection of ammonia as a ratiometric fluorescent sensor. A Tb-MOF based on an ESPT response linker was constructed, which can be used as a ratiometric fluorescence sensor for ammonia.
