Twisted-stacking MOF patterns with tailorable circularly polarized luminescence properties and encryption applications.

ABSTRACT: Optical active metal-organic frameworks (MOFs) with circularly polarized luminescence (CPL) functionalities, have recently gained extensive research interest. However, the luminescence dissymmetry factors (g_lum) of these materials are generally small, and the lack of patterning ability for most optical active MOFs greatly hinders their practical applications. Herein, we report a strategy to design twisted-stacking MOF patterns with a high g_lum (~0.4) and tailorable CPL performance by the combination of brush coating, bottom-up heteroepitaxial growth and twisted-stacking techniques. Specifically, two-dimensional (2D) programmable patterns of highly oriented MOF films could be achieved by the heteroepitaxial growth from pre-aligned Cu(OH)₂ nanowire (NW) templ
