Sobre IBD

Nowy chemoczujnik fluorescencyjny oparty na tiacalix[4]arenie, tiacalix[4]arene-N-(chinolin-8-ylo)acetamid (TCAN8QA) został zsyntetyzowany i scharakteryzowany za pomocą technik spektroskopowych 1H-NMR, FT-IR, ESI-MS i 13C-NMR. Stwierdzono, że TCAN8QA wykazuje wysoce selektywne zachowanie dla jonów F- spośród wszystkich innych anionów, np. Cl-, Br-, I-, PO4-3, OH-, H2PO4- i CH3COO- w widmach absorpcji, jak również w widmach emisji. Przesunięcie ku czerwieni i wygaszenie w widmach emisji stanowiące sygnaturę dla detekcji fluorków wynika z fotoindukowanego przeniesienia ładunku (PCT), które można przypisać deprotonacji kwaśnego protonu -NH w obecności jonów fluorkowych. Obserwacja jest również potwierdzona przez ESI-MS, NMR i analizę spektralną FTIR.
