A facile ratiometric sensing platform based on inner filter effect for hypochlorous acid detection

Multiple Interpenetrating Metal–Organic Frameworks with Channel-Size-Dependent Behavior for Selective Gossypol Detection and Perovskite Quantum Dot Encapsulation

“…Furthermore, the underlying process was established by comparing the three detection mechanisms of In-pdda-1 and In-pdda-2 . The overlap extents of Gsp UV absorption with the excitation bands of In-pdda-1 and In-pdda-2 are similar, and the FRET process that is associated with the overlap extent of In-pdda-1 is slightly larger than that of In-pdda-2 . − Considering the Gsp sensing performance of In-pdda-1 and In-pdda-2 , electron transfer may be the dominant mechanism.…”

Revealing the high efficiency of fluorescence quenching of rhodamine B by triangular silver nanodisks due to the inner filter effect mechanism

“…5,9 Together with FRET and NEST, uorescence quenching based on the inner lter effect (IFE) mechanism is also one of the most common in the design of uorescent sensors. 10,11 Here, IFE refers to the absorption of excitation and/or emission radiation by identical chromophores in a system. 12 In the beginning, the IFE was known as a source of errors in uorescence measurement.…”

The study of a novel high selectivity pyrenyl-based fluorescence probe with aggregation-induced emission characteristics for Fe3+ detection designed by a structure modulation strategy

“…31 In recent years, inner lter effect (IFE)-based sensors have become a surrogate because of the exible distance between chemosensors and analytes, short response time and simplicity in application. 32,33 Metal complexes based on 2-(1-pyrenyl)pyridine (pypyr) have manifested enticing photophysical properties due to their strong uorescence, high quantum yields and simple synthesis methods. [34][35][36] Inadvertently, we found that the excitation and emission wavelengths of pypyr are near the absorption peak of Fe 3+ .…”
