Summary:Using conjugate electrospinning technology to prepare Janus-structure nanofiber array and endow it with multifunctional characteristics is a very meaningful research topic. Here, photochromic adjustable magnetic bifunctional {[Eu(BA) 3 phen (EBP) + Tb(BA) 3 phen (TBP)]/polyvinylpyrrolidone (PVP)}//[Fe 3 O 4 /PVP] Janus-structure nanofiber array (defined as PM-JNA) is constructed by conjugate electrospinning. Janus-structure nanofibers are arranged in a micro-orientation, and most nanofibers have a special Janus structure. This structure confines the magnetic material and fluorescent material in two nanofibers, respectively, reduces the influence of magnetic material on fluorescence intensity, and significantly improves the fluorescence performance of the specimen. The using of conjugate electrospinning solves the problem of mutual diffusion of spinning liquid in the spinneret in parallel electrospinning and improves the separation efficiency of fluorescent substances and magnetic substances. Adjustable magnetic and luminous colors can be obtained by changing the contents of Fe 3 O 4 , EBP and TBP. Janus-structure nanofibers have been widely used in biological monitoring, medical imaging, nanodevices and multifunctional materials. Graphical abstract
