Electrospun polyfunctional switch-typed anisotropic photoconductive film endued with superparamagnetic-fluorescent performances

A new concept of switch-typed anisotropic photoconductive film (named as SAPF) is proposed for the first time. SAPF with top-bottom structure is constructed by electrospinning via using 2,7-dibromo-9-fluorenone (DF) of both fluorescence and photoconductivity as luminescent and conductive material.
