Embodiment

[0056] General method and equipment

[0057] (6,5) chiral enriched SWNTs (SG65) are commercially available from SouthWest NanoTechnologies. Ethylene gas (99.5% and 1.001% diluted with nitrogen), carbon monoxide gas and acetylene gas (99.5%) were purchased from Airgas. 5,10,15,20-Tetrakis(pentafluorophenyl)porphyrin (tpfppH 2 ) were purchased from Frontier Scientific. Perchloric acid (70%) was purchased from Sigma-Aldrich. Alumina (activated, neutral, Brockman grade I, ) were purchased from Alfa Aesar. Solvents were purchased from Sigma-Aldrich or Avantor Performance Materials (Macron Fine Chemicals or J.T. Baker) and used as received.

[0058] UV-Vis spectra were recorded on a Cary 4000 UV-Vis spectrophotometer. FT-IR spectroscopy (spectral analysis) was performed using a Thermo Scientific Nicolet 6700 FT-IR spectrometer (ATR mode, Ge). NMR spectra were recorded using a BrukerAvance 400MHz NMR spectrometer. Profiling measurements were acquired using a VeecoDektak 6M S...

Description

[0001] priority statement [0002] This application claims priority to US Application No. 61 / 946,872, filed March 2, 2014, which is incorporated by reference in its entirety. [0003] federally funded research or development [0004] This invention was made with Government support under Contract No. W911NF-13-D-0001 awarded by the Office of Army Research. The government has certain rights in inventions. technical field [0005] The invention relates to sensor (sensor, sensor) compositions based on metal complexes (metal complexes). Background technique [0006] Ethylene gas is important to industries related to manufacturing and agriculture. However, ethylene is a challenging chemical analyte to detect due to its small size and restricted chemical functionality. Existing available methods for determining ethylene concentration have been criticized for high cost and impractical implementation in the field. Contents of the invention [0007] In general, the chemically r...
