Orange-Red-Emitting Carbon Dots for Bilirubin Detection and Its Antibacterial Activity Against Escherichia coli and Staphylococcus aureus

“…The OR-CDs were further used for the fabrication of warm white LEDs. To achieve solid-state luminescence, OR-CDs were incorporated into the transparent matrix PVA. , It is to be noted that the use of the PVA matrix did not influence the fluorescence of OR-CDs . The resultant OR-CDs/PVA embedded fluorescent polymer film was directly coated onto a blue LED strip, and the outcomes are displayed in the inset of Figure .…”

“…To achieve solid-state luminescence, OR-CDs were incorporated into the transparent matrix PVA. 35,36 It is to be noted that the use of the PVA matrix did not influence the S5a. As shown in Figure S5a, the intensities of OR-CDs increase from pH 7 to 2, beyond which, from pH 8 to 12, it showed a continuous decrease.…”

“…However, in the present work, we found less overlapping of the spectra, which clearly rules out the existence of FRET mechanism in the fluorescence quenching process. 35 To ascertain the possible quenching mechanism, time-correlated single photon counting analysis of OR-CDs was performed in the absence or presence of an analyte molecule. Fluorescence lifetime measurements of OR-CDs in the absence or presence of bilirubin are shown in Figure 7b.…”

Aryl diazonium salts and benzene derivatives bearing two electron-donor substituents: chemical and mechanistic behaviours

“…27 Unlike 1,3,5-tris(N,N-dialkylamino)-benzene derivatives, just a few examples are reported for the electrophilic aromatic substitution involving 1,3-N,N-dialkylamino benzenes. [28][29][30][31] Based on these, we decided to study the azo-coupling reaction between these nucleophiles and para-substituted benzenediazonium salts to possibly obtain new compounds of interest for application in elds such as optoelectronics 32,33 and dyes 34 together with further mechanistic information on this kind of reaction.…”
