Simultaneous presence of static and dynamic component in the fluorescence quenching of Bis-MSB by CCl4 and aniline

Fluorescence quenching of newly synthesized biologically active coumarin derivative by aniline in binary solvent mixtures

“…4. Similar experimental results were also observed by others [5][6][7][8][9][10][11][12][13][14]. The positive deviation observed is not purely due to collisional, but may be due to the formation of either ground-state complex or static quenching process.…”

“…have been studied by several investigators [3][4][5][6][7][8][9][10][11][12][13][14][15] by steady-state and transient methods [16][17][18][19]. The quenching mechanism is important not only in physical science, but also in chemical, biological, and medical sciences.…”

“…However, in other cases, it is observed that the experimental results show positive deviation from a linear S-V equation [11][12][13][14][15][16]. This positive deviation is attributed to various processes like intersystem crossing, formation of charge-transfer complexes both at ground-and excitedstates, static and dynamic quenching, etc.…”

Acetylcholinesterase inhibition-based ultrasensitive fluorometric detection of malathion using unmodified silver nanoparticles

“…The Stern-Volmer plot obtained was found to be linear (Fig. 4), and the positive deviation observed for the higher concentration suggests the presence of both dynamic and static quenching [28]. The obtained Stern-Volmer constant suggested the strong fluorescence quenching effect of malathion on the emission intensity of AgNPs.…”

Fluorescence-quenching studies and temperature dependence of fluorescence quantum yield, decay time and intersystem crossing activation energy of TPB

“…As a continuation of our systematic studies of fluorescence quenching of laser dyes; we decided to carry out a similar study of 1, 1, 4, 4-tetraphenyl-1, 3-butadiene (TPB) [1][2][3][4][5][6]. Fluorescence quenching of organic molecules in solution by various quenchers like carbon tetrachloride [2][3][4][5], aniline [6,7], bromobenzene [8], metal ions [9] and halide ions [10], etc.…”
