Abstract

<abstract abstract-type="main" id="php12460-abs-0001"> <title>Abstract</title> <p>A new hybrid membrane was prepared by a facile method based on a highly luminescent lanthanide coordination polymer and agarose. The soft membrane was characterized by FT‐IR, PXRD, SEM and luminescence. It is found that the soft membrane is a highly selective and sensitive sensor, among 19 metal ion solutions of Fe<sup>3+</sup>, Mg<sup>2+</sup>, Li<sup>+</sup>, Ca<sup>2+</sup>, Zn<sup>2+</sup>, Cu<sup>2+</sup>, Ba<sup>2+</sup>, Mn<sup>2+</sup>, Ru<sup>3+</sup>, Cr<sup>3+</sup>, Ag<sup>+</sup>, Sr<sup>2+</sup>, Cd<sup>2+</sup>, Na<sup>+</sup>, Ni<sup>2+</sup>, Pb<sup>2+</sup>, Fe<sup>2+</sup>, Hg<sup>2+</sup> and Ca<sup>2+</sup>, only Fe<sup>3+</sup> quench the luminescence. The sensing results can be distinguished by the naked eye in daylight or by irradiation of a portable UV light at the scene. Mechanism studies reveal the sensing is due to the decomposition of the coordination polymer 1 which induced by slow permeation of Fe<sup>3+</sup>. Further studies found anions of <inline-formula><alternatives><inline-graphic mimetype="image" xlink:href="ark:/27927/pgj1d1j6qms" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /><mml:math altimg="urn:x-wiley:00318655:media:php12460:php12460-math-0001" overflow="scroll" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:msubsup><mml:mi mathvariant="bold">BO</mml:mi><mml:mrow><mml:mn mathvariant="bold">3</mml:mn></mml:mrow><mml:mo>−</mml:mo></mml:msubsup></mml:math></alternatives></inline-formula>, <inline-formula><alternatives><inline-graphic mimetype="image" xlink:href="ark:/27927/pgj1d1j6qjp" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /><mml:math altimg="urn:x-wiley:00318655:media:php12460:php12460-math-0002" overflow="scroll" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:msubsup><mml:mi mathvariant="bold">CO</mml:mi><mml:mrow><mml:mn mathvariant="bold">3</mml:mn></mml:mrow><mml:mrow><mml:mn mathvariant="bold">2</mml:mn><mml:mo>−</mml:mo></mml:mrow></mml:msubsup></mml:math></alternatives></inline-formula>, <inline-formula><alternatives><inline-graphic mimetype="image" xlink:href="ark:/27927/pgj1d1j6rfj" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /><mml:math altimg="urn:x-wiley:00318655:media:php12460:php12460-math-0003" overflow="scroll" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:msub><mml:mi mathvariant="bold">H</mml:mi><mml:mn mathvariant="bold">2</mml:mn></mml:msub><mml:msubsup><mml:mi mathvariant="bold">PO</mml:mi><mml:mrow><mml:mn mathvariant="bold">4</mml:mn></mml:mrow><mml:mo>−</mml:mo></mml:msubsup></mml:mrow></mml:math></alternatives></inline-formula>, Br<sup>−</sup>, Cl<sup>−</sup>, <inline-formula><alternatives><inline-graphic mimetype="image" xlink:href="ark:/27927/pgj1d1j6rcf" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /><mml:math altimg="urn:x-wiley:00318655:media:php12460:php12460-math-0004" overflow="scroll" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:msubsup><mml:mi mathvariant="bold">ClO</mml:mi><mml:mrow><mml:mn mathvariant="bold">4</mml:mn></mml:mrow><mml:mo>−</mml:mo></mml:msubsup></mml:math></alternatives></inline-formula>, <inline-formula><alternatives><inline-graphic mimetype="image" xlink:href="ark:/27927/pgj1d1j6rbw" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /><mml:math altimg="urn:x-wiley:00318655:media:php12460:php12460-math-0005" overflow="scroll" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:msub><mml:mi mathvariant="bold">H</mml:mi><mml:mn mathvariant="bold">2</mml:mn></mml:msub><mml:msubsup><mml:mi mathvariant="bold">PO</mml:mi><mml:mrow><mml:mn mathvariant="bold">4</mml:mn></mml:mrow><mml:mo>−</mml:mo></mml:msubsup></mml:mrow></mml:math></alternatives></inline-formula>, I<sup>−</sup>, <inline-formula><alternatives><inline-graphic mimetype="image" xlink:href="ark:/27927/pgj1d1j6r77" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /><mml:math altimg="urn:x-wiley:00318655:media:php12460:php12460-math-0006" overflow="scroll" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:msubsup><mml:mi mathvariant="bold">IO</mml:mi><mml:mrow><mml:mn mathvariant="bold">3</mml:mn></mml:mrow><mml:mo>−</mml:mo></mml:msubsup></mml:math></alternatives></inline-formula> and <inline-formula><alternatives><inline-graphic mimetype="image" xlink:href="ark:/27927/pgj1d1j6r4k" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /><mml:math altimg="urn:x-wiley:00318655:media:php12460:php12460-math-0007" overflow="scroll" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:msubsup><mml:mi mathvariant="bold">NO</mml:mi><mml:mrow><mml:mn mathvariant="bold">3</mml:mn></mml:mrow><mml:mo>−</mml:mo></mml:msubsup></mml:math></alternatives></inline-formula> will not quench the luminescence of the hybrid membrane, which imply that other anions in water would not disturb the detection result.</p> </abstract>
