Colored polymer-reinforced metal-organic framework microparticles with high charge-to-mass ratio for electrophoretic display.

ABSTRACT: Besides high porosity and controllable structure, metal-organic framework (MOF) has some natural advantages for color electrophoretic particles: easy modification, controllable morphology, low and adjustable density, and high charge density, as well as rich, vivid, and stable colors. Therefore, we first integrated the four colored MOF microparticles and polyelectrolytes into the blue, reddish-brown, green, and purple electrophoretic particles to construct the two-color stable dispersions in nonpolar isododecane as the electrophoretic inks. Here, the surface modification of polyethyleneimine (PEI) chains based on non-covalent interaction rendered these MOF microparticles fully reinforced to ~+30 mV in Zeta potential and over 3.6 × 10^-10 m² V^-1 s^-1
