Highly oriented three-dimensional metal−organic framework (MOF) crystals with a pillared-layer structure were prepared on a metal ion-doped polymer substrate. This approach allowed the formation of MOF crystals with controlled crystalline orientation in a one-pot reaction facilitated by the control of the chemical interaction between the framework components and polymer substrate. Further, this approach provides a new concept for the one-pot synthesis of oriented MOF crystals and furthers the fundamental understanding of the crystal growth mechanism based on self-assembly processes on two-dimensional support substrates.
