Computational Studies

Upon the gradual addition of Al3+ to a solution of HL, the sensor showed a large fluorescence enhancement at 420 nm. The reason for this phenomenon is that the addition of Al3+ to the solution of HL results in the formation of a 1 : 1 stoichiometry of the binding mode of L–Al which inhibits photoinduced electron transfer (PET).

The Relationship

Hydrogen peroxide (H2O2) plays an important role in the human body and monitoring its level is meaningful due to the relationship between its level and diseases. A fluorescent sensor (CMB) based on coumarin was designed and its ability for detecting hydrogen peroxide by fluorescence signals was also studied. The CMB showed an approximate 25-fold fluorescence enhancement after adding H2O2 due to the interaction between the CMB and H2O2 and had the potential for detecting physiological H2O2. It also showed good biocompatibility and permeability, allowing it to penetrate cell membranes and zebrafish tissues, thus it can perform fluorescence imaging of H2O2 in living cells and zebrafish. This probe is a promising tool for monitoring the level of H2O2 in related physiological and pathological research.
