abstract |
Porphyrin-chalcone derivatives with potential cation sensing ability have been studied by ESI-MS and multistage ESI-MS. The presence of conjugated C=C and C=O double bonds in the chalcone moiety is responsible for the formation of diagnostic fragment ions common to all the studied meta and para chalcones. The ortho isomers show different fragmentation patterns that can be explained by different electronic charge distributions. (C) 2015 Elsevier B.V. All rights reserved. |
