Aggregation induced emission properties of naphthalimide–coumarin conjugates with various intermolecular linkages

Disaggregation of a sumanene-containing fluorescent probe towards highly sensitive and specific detection of caesium cations

“…In contrast, no detectable peak was found for the CHCl 3 solution of 5, since 5 was in the molecular well-dissolved state. 27 The emission spectra for the lyophilized aggregates were also measured (black dotted lines in Fig. 2a and Fig.…”

Insight on Mercapto-Coumarins: Synthesis and Reactivity

“…Choi and co-workers developed a naphthalimide–coumarin conjugate (NC) typically through thioether linkage ( Scheme 29 ) [ 81 ]. 6-Bromo-2-butyl-benzo[de]isoquinoline-1,3-dione ( 82 ) reacted with 7-mercapto-4-methyl coumarin ( 50 ) in the presence of potassium carbonate to give 2-butyl-6-((4-methyl-2-oxo-2 H -chromen-7-yl)thio)-1 H -benzo-[de]isoquinoline-1,3(2 H )-dione ( 83 ) ( Scheme 29 A) [ 81 ]. The molecular flexibility and the aggregation of the nanoparticles of the investigated compound ( 83 ) enhanced the aggregation-induced emission ( Scheme 29 B) [ 81 ].…”

Bis(thio)carbohydrazone Luminogens with AIEE and ACQ Features and Their In Silico Investigations with SARS‐CoV‐2

“…Bioactive compounds showing aggregation induced emission (AIE) features offer huge opportunities for the analysis of bioactive species and for monitoring complicated biological processes [1] . AIE phenomenon has attracted tremendous research interest in the scientific community due to wide range of applications such as chemosensors, biomedical imaging, photodynamic therapy, optoelectronic devices, etc [1–7] . Conventional luminescence probes encounter aggregation caused quenching (ACQ) problems and are thus limited in usage.…”

“… [1] AIE phenomenon has attracted tremendous research interest in the scientific community due to wide range of applications such as chemosensors, biomedical imaging, photodynamic therapy, optoelectronic devices, etc. [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ] Conventional luminescence probes encounter aggregation caused quenching (ACQ) problems and are thus limited in usage. Development of AIE in the field of biomedicine has brought huge opportunities for the analysis of bioactive species, diagnosis of diseases by monitoring complicated biological processes, and the elucidation of key physiological and pathological behaviors.…”
