Supporting Information Iodide-Selective Synthetic Ion Channels Based on Shape-Persistent Organic Cages

摘要: All reagents were purchased from commercial suppliers and used without further purification unless stated otherwise. All air-sensitive reactions were performed using oven-dried glassware under an inert atmosphere of argon. A syringe or cannula was used to transfer airsensitive solvents and solutions. Dichloromethane was distilled from calcium hydride. 8-hydroxypyrene-1, 3, 6 trisulfonic acid, trisodium salt (HPTS) dye, lucigenin dye, HEPES buffer, inorganic salts, inorganic bases and Triton X-100 were purchased from Sigma-Aldrich. Millipore grade water was used to prepare buffer solutions. All the lipids were purchased from Avanti Polar Lipids, Inc.(USA) and stored in a refrigerator at-20 C. All NMR spectra were recorded at ambient temperature using a Bruker DRX 500 MHz or 850 MHz spectrometer. Solvent peaks were used as a standard reference peak for NMR spectra. Fluorescence spectra were recorded on a SHIMADZU RF-5301PC spectrofluorophotometer equipped with a magnetic stirrer using a 3 mL quartz cuvette. Fluorescence and single channel conductance data were processed using Origin 8.5 program. Mass spectrometry was performed on an ABI 4700 Proteomics Analyser MALDI-TOF instrument or Thermofisher LTQ-ESI ion trap. UV-Vis absorption spectra were recorded using an Agilent Cary 5000 UV-Vis-NIR Spectrophotometer. IR spectra were recorded using a Agilent Technologies Cary 600 Series or VERTEX 70/70v FT-IR Spectrometer. Peaks are reported in wavenumbers (cm-1) as strong (s), medium (m), weak (w), and broad (br). Elemental analyses were carried out in Korea Basic Science Institute, Busan, Korea …
