Ge 111 monochromator

All crystalline phases were characterized by powder X-ray diffraction, thermal, spectroscopic and elemental analyses.
X-ray powder patterns were recorded in transmission mode on a Stoe Stadi-P diffractometer equipped with a Ge(111) monochromator and a position-sensitive detector using Cu Kα₁ radiation. The sample was rotated during the measurement.
Thermogravimetric analysis (TGA) was carried out using a TGA 92 system (SETERAM Instrumentation). Differential scanning calorimetric (DSC) measurements were performed with a DSC 131 systems (SETERAM Instrumentation) in the temperature window from room temperature up to 500°C.
Spectroscopically the samples were characterized by FTIR using a Shimadzu FTIR-8300 measuring in transmission mode; LDI-TOF-MS using a Voyager-DE STR (Applied Biosystems Inc.) using a nitro­gen laser with 337 nm and 10 ns; all liquid ¹H NMR studies were carried out using an Avance 250 MHz NMR spectrometer (Bruker) at 300 K in d₂-sulfuric acid.
Elemental analyses (EA, only C:H:N quantification) were performed on a vario MICRO cube from Elementar Analytical Systems GmbH.

The DFQ sample was prepared between two polymer films. PXRD data were recorded at room temperature with Cu Kα₁ radiation in transmission mode on a Stoe Stadi-P diffractometer equipped with a primary Ge(111) monochromator and a linear position-sensitive detector. The sample was rotated during the measurement. Data were collected in a 2θ range from 2.00 to 79.99° with a resolution of 0.01° per step, resulting in 7800 data points. The software WinX^Pow (Stoe & Cie, 2005 ▸ ) was used for data collection and reduction.
