General
IR spectra were recorded on a Bruker Tensor FT-IR (ATR sampling accessory)
spectrophotometer, and electronic spectra on an Agilent 8453 UV-Vis spectrophotometer.
Mass spectra were measured on a Bruker Microflex LT MALDI-TOF MS and Agilent 6460
LC-MS/MS. Melting point was determined on an Electrothermal Gallenkamp apparatus.
