Vnmr 500

Infrared spectra were recorded on a Perkin-Elmer Spectrum One. Proton nuclear magnetic resonance (δ H ) spectra were recorded on Agilent Technologies 400 MR (400 MHz) or Varian VNMR500 (500 MHz) spectrometers. All chemical shifts are quoted on the δ-scale in ppm using residual solvent as an internal standard. High-resolution mass spectra were recorded with a BrukermaXis 3G UHR-TOF mass spectrometer. Thermogravimetric analysis (TGA) was performed with an Alphatech SDT Q600 TGA/DSC apparatus, on 6-8 mg of purified, dry materials (the sample holder used was alumina crucible), under N 2 (with a flow rate of 50 mL min -1 ), recording data from 25 to 1000 °C at a heating rate of 10 °C min -1 . Elemental analyses were performed by the Campbell Microanalytical Laboratory at the University of Otago. TEM images of AuNPs were obtained using a Philips CM200 TEM operating at 200 kV. Samples for TEM imaging were prepared by dropping 2 µL of a freshly prepared solution of nanostructured Au onto a carbon-coated copper grid (300 mesh) and drying at room temperature. UV-Vis absorption spectra and kinetic measurements were performed using a Varian Cary 100 UV-Vis spectrophotometer.

All experiments and manipulations were carried out under an inert nitrogen atmosphere using standard glovebox or Schlenk techniques unless otherwise indicated. NMR spectra were obtained on a Varian VNMR 700 (699.76 MHz for 1 H; 175.95 MHz for 13 C), a Varian VNMR 500 (500.09 MHz for 1 H; 470.56 MHz for 19 F) or a Varian VNMR 400 spectrometer (399.54 MHz for 1 H; 128.187 for 11 B). 1 H and 13 C chemical shifts are reported in parts per million (ppm) relative to TMS, with the residual solvent peak as an internal reference. 19 F chemical shifts and 11 B chemical shifts are reported in ppm and are referenced on a unified scale, where the single primary reference is the frequency of the residual solvent peak in the 1 H NMR spectrum. Abbreviations used in the NMR data: s, singlet; ; br, broad signal. Mass spectral data were obtained on a Micromass magnetic sector mass spectrometer in electrospray ionization mode. X-ray crystallographic data were collected on a Bruker SMART APEX-I CCD-based X-ray diffractometer. Electronic spectra were collected with a Shimadzu UV-1601 UV-VIS spectrometer (190-1100 nm) with a 4 mL sealed quartz cuvette. Flash chromatography was conducted using a Biotage Isolera One system with cartridges containing high performance silica gel.
