Fluorescence responses on ion recognition with 2-(4-dialkylaminophenyl)ethoxyantimony(V) tetraphenylporphyrin
The effects of metal ions on the fluorescence spectra of 2-phenylethoxyhydroxyantimony(V) tetraphenylporphyrin hexafluorophosphate (1a-c) involving azacrown ether on axial ligands were investigated. Trivalent metal ions such as Al3+, In3+, Ga3+, and Lu3+ which undergo the complexation with the azacrown ether remarkably enhanced the fluorescence quantum yields.
