The additive effects of metal cations on the fluorescence quantum yield (φf) were investigated for weakemissive amino(tetraphenylporphyrinato) antimony(V) bromide (1). When the μmol dm-3 of trivalent metal cations such as Al3+, Ga3+, In3+, and Lu 3+ were added to MeCN solution of 1, the φf was remarkably enhanced. The dependences of Soret band shift and φf upon the addition of trivalent metal cations revealed that a transition from S2 state to the partially charge-shifted state was prevented by coordinating trivalent metal cations to the axial nitrogen atom of 1. 1 worked as a selective fluorosensor for detecting μmol dm-3 trivalent metal cations.

In order to develop water-soluble porphyrins, alkyloxo-(methoxo) porphyrinatoantimony bromides (alkyl = decyl, dodecyl, and octadecyl) were prepared. These complexes have more than 200 mg/100 g of solubility in aqueous solution. From the analysis of absor
