METHODOLOGICAL INFORMATION
-
Description of methods used for collection-generation of data:
NMR spectra: recorded on Bruker DPX360 (360 MHz for 1H NMR), Bruker Ascend 300 MHz (300 MHz for 1H NMR) and Bruker Ascend 400 MHz (400 MHz for 1H NMR) spectrometers.
IR spectrum: recorded on Bruker Tensor 27 Golden Gate spectrometer with a diamond tip.
MS spectrum: recorded on Bruker Esquire 3000+ spectrometer using ESI and APCI.
UV-Vis spectra: recorded on Agilent HP 8453 spectrophotometer using 1 cm quartz cuvettes.
SEM images: recorded on FEI Quanta 650 ESEM microscope applying a 5 kV voltage.
DMA data: obtained with a Discovery HR-2 rheometer at room temperature (frequency = 1 Hz).
-
Methods for processing the data:
NMR, MS and IR data are presented raw, UV-Vis spectra are presented after baseline substraction.
-
Instrument- or software- specific information needed to interpret the data:
NMR spectra: Bruker Topspin 4.1.1 or higher, or MestReNova 12.0.0 or higher.
IR spectrum: OriginPro 8.1 or higher, or any other graphic representation program, such as Microsoft Excel.
MS spectrum: Adobe Acrobat Reader.
UV-Vis spectra: OriginPro 8.1 or higher, or any other graphic representation program, such as Microsoft Excel.
DMA data: OriginPro 8.1 or higher, or any other graphic representation program, such as Microsoft Excel.
