Abstract Isophthalonitrile derivatives (IPNs) have emerged as promising organic photocatalysts due to their efficiency and accessibility; however, inherent lability under light‐induced conditions poses significant challenges in monitoring transformation pathways. Understanding these pathways is crucial for optimizing photocatalytic processes enhancing reaction efficiency. In this study, we present a novel approach utilizing electrospray ionization mass spectrometry (ESI‐MS) visualize cyanoarene by taking advantage of specific supramolecular interaction with bromide anions. Our findings reveal that ions facilitate the detection IPNs products high sensitivity selectivity, even complex environments. The predominantly occurs gas phase, minimizing interference solution‐based transformations. developed anion‐enhanced (AED‐ESI‐MS) not only provides real‐time insights into photocatalyst behavior but also opens new possibilities detailed mechanistic investigation light‐driven reactions. proposed AED‐ESI‐MS using other anions may offer broad applicability be worth studying further across various systems.
