Di-aeolotropic conductive left-to-right structured special Janus array membrane (SJ-J-AM) simultaneously with up-/down-converting fluorescence and magnetism was built via electrospinning. SJ-J-AM consists of {[CoFe2O4/polymethylmethacrylate (PMMA)@[poly(3,4-ethylenedioxythiophene) (PEDOT)/PMMA]}//[NaYF4:Yb3+, Er3+/PMMA] special Janus array film with up-converting luminescence (UL) as left-side (U-SJAF) and [PEDOT/PMMA]//[Tb(acac)3bipy/PMMA] Janus array film with down-converting luminescence (DL) as right-side (D-JAF). Microscopically, Janus nanobelt with concentric//uniaxial structure and common Janus nanobelt, as building unit, efficaciously confines functional substances to their respective area, averting reciprocal affect among conduction, magnetism and luminescence to earn enhanced fluorescence and strong aeolotropic conduction, the luminescence intensity of U-SJAF and D-JAF are respectively 6.2 and 7 times than that of composites array film with UL and DL. Macroscopically, SJ-J-AM fulfills the portion of UL and DL regions, and the tight connection between U-SJAF and D-JAF with single aeolotropism conductance makes SJ-J-AM to hold di-aeolotropic conduction, realizing the high integration of micro- and macro-portion in SJ-J-AM.

通过顺序同轴和并排静电纺丝制备具有上/下转换荧光和磁性的双异向导电 Janus 纳米带
通过静电纺丝构建了可同时具有上/下转换荧光和磁性的双异向导电从左到右结构的特殊 Janus 阵列膜 (SJ-J-AM)。SJ-J-AM由{[CoFe 2 O 4 /聚甲基丙烯酸甲酯(PMMA)@[聚(3,4-乙烯二氧噻吩)(PEDOT)/PMMA]}//[NaYF 4 :Yb 3+ , Er 3+ /PMMA ] 具有上转换发光 (UL) 作为左侧 (U-SJAF) 和 [PEDOT/PMMA]//[Tb(acac) 3的特殊 Janus 阵列薄膜bipy/PMMA] 具有下转换发光 (DL) 作为右侧 (D-JAF) 的 Janus 阵列薄膜。微观上,具有同心//单轴结构的Janus纳米带和普通的Janus纳米带作为建筑单元,有效地将功能物质限制在各自的区域内,避免传导、磁性和发光之间的相互影响,从而获得增强的荧光和强的各向异性传导。 U-SJAF和D-JAF分别是UL和DL复合阵列薄膜的6.2倍和7倍。宏观上,SJ-J-AM满足了UL和DL区域的部分,而U-SJAF和D-JAF之间的紧密连接,单一的各向异性电导,使SJ-J-AM保持了非向异性传导,实现了高集成度。 SJ-J-AM 中的微观和宏观部分。
