Mussel-inspired polydopamine (PDA) chemistry was exploited, for the first time, to regulate the contra-diffusion synthesis of 1D metal-organic framework (MOF) superstructures in the channels of polycarbonate track-etched membranes. The PDA modified template channels facilitate controllability for the heterogeneous nucleation and interfacial growth of various MOFs. Well-defined 1D hybrid MOF nanotubes with a high aspect ratio up to 40 and length of 10 mu m were successfully obtained. Potential application of the composite membrane for decontamination of organic dyes was demonstrated by a facile filtration method. This study provides new insights into the surface chemistry directed growth behavior of MOFs on polymeric templates. Moreover, the methodology of PDA chemistry mediated contra-diffusion synthesis opens a new avenue to fabricate diverse 1D superstructures of MOFs and other functional materials.
