Exploring triphenylene ethynylene structures as MALDI matrices


MALDI continues to be a useful method of mass spectrometry for a wide range of biological molecules. This poster explores the use of several preliminary triphenylene ethynylene (TPEE) structures that may be useful as matrices in MALDI spectrometry. Three electron-donating TPEEs were synthesized and analyzed and two electron-withdrawing TPEEs were synthesized and compared to TCNQ. One of the electron-donating matrices and one of the electron-withdrawing matrices showed significant promise as effective MALDI matrices, demonstrating minimal fragmentation, low matrix peaks, and high analyte signal strength.
