All the reagents and solvents used in this work were purchased from commercial sources & used without further purification. Solid state FT-IR spectra of 400–4000 cm−1 range were collected from Nicolet MAGNA-IR 750 spectrometer with sample prepared as KBr pellets. Elemental analyses were performed with Perkin-Elmer 2400 series CHN analyser. 1H and 13C NMR spectrum were carried out by 400 MHz and 500 MHz Bruker NMR spectrometers respectively dissolving sample in DMSO-d6 solvent. Mass spectra was collected by Q-ToF Micro YA263 high resolution (Waters Corporation) mass spectrometer by positive ion mode electrospray ionization and the spectra were collected in methanol. Absorption spectra were collected with a Jasco V-630 spectrophotometer. Photoluminescence spectra were collected at room temperature using Agilent Cary Eclipse & Hitachi, F-2500 fluorescence spectrophotometer and Horiba scientific TCSPC.

NMR spectroscopy was carried out on a Bruker
500 MHz using CDCl3 as a solvent. The NMR spectra of the
solutions in CDCl3 were calibrated to tetramethylsilane
as the internal standard (δH 0.00). MALDI-TOF experiment was
carried out on a Q-Tof Micro YA263 high-resolution (Waters Corporation)
mass spectrometer. The IR spectrum was obtained from the IR PerkinElmer
spectrometer at a nominal resolution of 2 cm–1.
Micro-Raman spectrum was obtained from Raman Spectrometer, Horiba
Jobin Yvon, HR 800 double grating. Field emission SEM and cryo-SEM
analyses were performed on a Zeiss microscope; SUPRA 55VP-Field Emission
Scanning Electron Microscope. The rheological measurement was carried
out on rheometer AR 2000 (TA instrument) using a steel parallel plate
at 25 °C with a 1.0 mm gap spacing for gel samples. TGAs were
carried out using PerkinElmer thermogravimetric analyzer at a heating
rate 10 °C/min. The temperature range was 50–600 °C.
UV–vis absorption measurements were carried out on PerkinElmer
Lambda-35 UV–vis spectrometer.

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.
