Abstract:
This study presents the first synthesis and characterization of quinoliporphyrin (6), a unique aromatic monoanionic macrocycle featuring a quinoline unit within the porphyrinoid core. Previously, quinoline-containing porphyrins had their quinoline units positioned at peripheral locations. This structural feature exhibits exclusive reactivity with Cu2+, leading to rapid degradation at μM concentrations within 30 min at room temperature and the formation of a fluorogenic product (7). Such mild and rapid reactivity is attributed to the presence of the quinoline core.
