Incorporating unsubstituted phthalocyanine and dibutylamino-substituted phthalocyanine into sandwich-type rare earth compounds has provided a heteroleptic bis(phthalocyaninato) trivalent holmium analogue. The rich redox states of sandwich-type tetrapyrole-based metal compounds lead to the formation of [(Pc)Ho{Pc{N(C₄H₉)₂}₈}]^. (1) and [(Pc)Ho{Pc[N(C₄H₉)₂]₈}]⁻ ⋅ [(C₄H₉)₄N]⁺ (2) as a neutral unprotonated and reduced state, respectively. The detailed sandwich-type structures of these two homologs with different redox states are disclosed using single crystal X-ray diffraction analyses. In addition, the differences in these two compounds with/without one radical have been ascertained by fundamental spectroscopic instruments, enabling the adjustment of the corresponding static magnetic behaviors and nonlinear optical properties owing to the presence/absence of radical-Ho(III) interaction and different electron cloud density delocalized around 1 and 2.

杂配双(酞菁)钬化合物的磁行为和非线性光学性质

将未取代的酞菁和二丁基氨基取代的酞菁结合到夹心型稀土化合物中，提供了一种杂配双（酞菁）三价钬类似物。夹心型四吡咯基金属化合物的丰富氧化还原状态导致 [(Pc)Ho{Pc{N(C ₄ H ₉ ) ₂ } ₈ }] 的形成^。( 1 ) 和 [(Pc)Ho{Pc[N(C ₄ H ₉ ) ₂ ] ₈ }] ⁻ ⋅ [(C ₄ H ₉ ) ₄ N] ⁺ ( 2) 分别作为中性未质子化和还原状态。使用单晶 X 射线衍射分析公开了这两种具有不同氧化还原状态的同系物的详细夹心型结构。此外，这两种化合物在有/没有一个自由基的情况下的差异已被基础光谱仪器确定，由于自由基-Ho(III)相互作用的存在/不存在和不同的电子云密度在1和2附近离域。
