NMR spectra were performed on a Bruker ARX 400 NMR spectrometer. Electrospray ionization mass spectrometry (ESI-MS) was performed on a Proteome X-LTQ. Particle size and size distribution were determined by laser light scattering (LLS) with a particle size analyzer (90 Plus, Brookhaven Instruments Co., United States) at a fixed angle of 90° at room temperature. The zeta potential was determined by a Malvern Zetasizer Nano ZS90 (Worcestershire, UK). TEM images were obtained from a JEOL JEM-2010 transmission electron microscope with an accelerating voltage of 200 KV. UV-vis absorption spectra were taken on a Shimadzu Model UV-1700 spectrometer. Photoluminescence (PL) spectra were measured on a Perkin-Elmer LS 55 spectrofluorometer. All UV and PL spectra were collected at 24 ± 1 °C.

All the chemicals were purchased
from a commercial vendor and used directly without further purification.
Dry dichloromethane was distilled over CaH2. All 1H NMR and 13C NMR spectra were recorded on a Bruker ACF-400
MHz NMR spectrometer with CDCl3 or (CD3)2SO (DMSO-d6) as the solvent. Chemical
shifts are described
in parts per million, which are referenced according to residual solvent
for 1H NMR (7.26 ppm for CDCl3 and 2.50 ppm
for DMSO-d6) and 13C NMR (77.0
ppm for CDCl3 and 40.0 ppm for DMSO-d6). HRMS (ESI) spectra were recorded by the AmaZon X LC-MS.
UV–vis absorption spectra were recorded on a Shimadzu Model

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
