Sobre IBD

Un nuovo chemiosensore fluorescente a base di tiacalix[4]arene, il tiacalix[4]arene-N-(chinolin-8-il)acetammide (TCAN8QA), è stato sintetizzato e caratterizzato mediante tecniche spettroscopiche 1H-NMR, FT-IR, ESI-MS e 13C-NMR. È stato scoperto che il TCAN8QA mostra un comportamento altamente selettivo per gli ioni F- tra tutti gli altri anioni, ad esempio Cl-, Br-, I-, PO4-3, OH-, H2PO4- e CH3COO- negli spettri di assorbimento e di emissione. Lo spostamento verso il rosso e lo spegnimento negli spettri di emissione che costituiscono la firma per il rilevamento del fluoro è dovuto al trasferimento di carica fotoindotto (PCT), che può essere attribuito alla deprotonazione del protone acido -NH in presenza di ioni fluoro. L’osservazione è confermata anche dall’analisi spettrale ESI-MS, NMR e FTIR.
