(tBu)4M(ii)Phthalocyanines (M = Co(ii), Ni(ii), Cu(ii)) revisited: self-assembled nanosheets for enhanced electrochemically catalyzed hydrogen evolution

Abstract

Three M(II)(tBu)₄phthalocyanines (M = Co(II), Ni(II), Cu(II)) were revisited and constructed as nanosheets through solvent and ultrasonication dual-controlled aggregations. These M(II)Pc molecules have exhibited higher electrochemical catalytic efficiency compared with amorphous metallophthalocyanine molecules, which provides new insights into phthalocyanine based material catalysis.
