Abstract

1H and 13C NMR spectra were recorded on a Bruker Avance III-500 or III-600 NMR spectrometer (chemical shifts with respect to (TMS) = 0 ppm). Solution electronic absorption and emission spectra were recorded on an Agilent 8453 spectrophotometer and Shimadzu 5301PC spectrofluorophotometer, respectively; a Perkin Elmer Spectrum Two UATR instrument was used to… (More)
