比较了金属酞菁（Ⅱ）（Co，Ni，Cu）在导电和绝缘基底Au（111）和有机铁电聚偏氟乙烯（PVDF）上的电子结构。不同的3d轨道贡献的金属酞菁导致不同的基板相互作用，和不同的分子轨道偏移。当酞菁钴（CoPc）吸附在铁电PVDF表面时，其光电发射和逆光电发射谱表明，CoPc与Au（111）和PVDF的结合更强，从而在PVDF表面形成优先的平面构型，而酞菁镍（NiPc）和酞菁铜（CuPc）则没有观察到这种构型.
We compare the electronic structures of metal(II) (Co, Ni, Cu) phthalocyanines adsorbed on conducting and insulating substrates: Au(111) and the organic ferroelectric polyvinylidene fluoride (PVDF). The different 3d orbital contributions to the metal phthalocyanines result in different substrate interactions, and different molecular orbital offsets. When adsorbed on the ferroelectric PVDF surface, the photoemission and inverse photoemission spectra suggest that cobalt phthalocyanine (CoPc) bonds more strongly to both Au(111) and PVDF, resulting in a preferential planar configuration on the PVDF surface, not observed with nickel phthalocyanine (NiPc) and copper phthalocyanine (CuPc).
