Abstract：

In　this　work,　a　novel　zinc　phthalocyanine　tetrasulfonic　acid　(ZnTsPc)-functionalized　graphene　nanocomposites　(f-GN)　was　synthesized　by　a　simple　and　efficient　electrostatic　self-assembly　method,　where　the　positive　charged　GN　decorated　by　(3-aminopropyl)　triethoxysilane　(APTES)　was　self-assemblied　with　ZnTsPc,　a　two　dimensional　(2-D)　molecules.　It　not　only　enhanced　its　stability　for　the　hybrid　structure,　but　also　avoided　the　reaggregation　of　ZnTsPc　or　f-GN　themselves.　Based　on　layered　ZnTsPc/f-GN　nanocomposites　modified　glassy　carbon　electrode,　a　rapid　and　sensitive　sensor　was　developed　for　the　determination　of　bisphenol　A　(BPA).　Under　the　optimal　conditions,　the　oxidation　peak　current　increased　linearly　with　the　concentration　of　BPA　in　the　range　of　5.0　×　10-　8　to　4.0　×　10-　6　M　with　correlation　coefficient　0.998　and　limits　of　detection　2.0　×　10-　8　M.　Due　to　high　absorption　nature　for　BPA　and　electron　deficiency　on　ZnTsPc/f-GN,　it　presented　the　unique　electron　pathway　arising　from　π-π　stackable　interaction　during　redox　process　for　detecting　BPA.　The　sensor　exhibited　remarkable　long-term　stability,　good　anti-interference　and　excellent　electrocatalytic　activity　towards　BPA　detection.　©　2015　Elsevier　B.V.
