PURPOSE:To obtain a porphyrin/indium complex, comprising a specific chemical structure, having the ionic sensitivity to chloride ions in a biological bumor, excellent in water resistance, sensitivity and selectivity and useful for an anion- sensitive membrane, etc. CONSTITUTION:This porphyrin/indium complex is expressed by formula I [R<1> and R<2> each is H or a lower alkyl; R<2> is H or an (substituted)aryl; X is an atomic group forming a hallde ion or a stable anion; Y is a 2-12C bivalent hydrocarbon; Z is a monovalent hydrophobic organic group] such as a compound expressed by formula II. Furthermore, this anion-sensitive membrane is obtained by comprising preferably 2-10wt.% complex in a polymeric compound such as PVC or PS and a plasticizer such as dioctyl phthalate. |
