Bruker NMR instruments operating at 600 and 800 MHz were used to gather H NMR and 13 C NMR spectra. Mass spectrometry data were obtained with an electrospray ionisation (ESI) mass spectrometer in the positive ionisation mode on Thermo Scientific LTQ Orbitrap XL. The buffer's pH was measured using a Eutech Instrument pH 2700 model metre. Using a Shimadzu UV-visible spectrophotometer (U2600), absorption spectra were recorded. A Horiba fluorolog spectrofluorometer with a 3 nm slit for excitation and emission was used to obtain the fluorescence spectra. The CCK-8 assay's absorbance was measured using a Thermovarioskanlux multimode microplate reader. A laser scanning confocal fluorescence microscope (Olympus FV-3000-IX-81) was used to acquire the fluorescence images.
