摘要: 通过在铽的酞菁卟啉混杂三层的卟啉周边共价连接体积庞大的笼型倍半硅氧烷(POSS),得到了首个包含POSS的混杂三层Tb₂(Pc)[T(OPOSS)₄PP]₂(1)[H₂Pc=phthalocyanine;H₂T(OPOSS)₄PP=5,10,15,20-tetra{[[N-[heptakis(isobutyl)propoxy]phenyl]octasiloxane]}porphyrin]。为了对比研究,同时合成了类似的三层化合物Tb₂(Pc)(TPP)₂(2)(H₂TPP=5,10,15,20-tetraphenyporphyrin)。尤其值得注意的是,在没有外加磁场的条件下,Tb₂(Pc)[T(OPOSS)₄PP]₂(1)和Tb₂(Pc)(TPP)₂(2)分别表现出单分子磁体和非单分子磁体的性质,这充分说明了共价连接均匀分布的POSS基团有效地分离了磁性核心,从而改善了酞菁卟啉混杂三层的磁性。

Abstract: Bulky inorganic polyhedral oligomeric silsesquioxanes (POSS) moieties were introduced onto the porphyrin periphery in mixed (phthalocyaninato) (porphyrinato) terbium molecule, giving POSS-involved hybrid triple-decker complex Tb₂(Pc)[T(OPOSS)₄PP]₂ (1) [H₂Pc=phthalocyanine; H₂T(OPOSS)₄PP=5, 10, 15, 20-tetra{[[N-[heptakis(isobutyl)propoxy]phenyl]octasiloxane]}porphyrin]. For comparative study, triple-decker analogue Tb₂(Pc)(TPP)₂ (2) (H₂TPP=5, 10, 15, 20-tetraphenyporphyrin) was also prepared and structurally characterized. In particular, Tb₂(Pc)[T(OPOSS)₄PP]₂ (1) and Tb₂(Pc)(TPP)₂ (2) were revealed to display intrinsic single molecule magnet (SMM) and non-SMM (or field-induced) characteristic, respectively, at zero Oe (or a 3.0 Oe ac field), clearly indicating the effect of the covalently linked, homogenously dispersed POSS moieties on effectively separating the magnetic cores and improving the magnetic property of triple-decker compounds.
