Mechanochromic luminescence molecules show great appeal in the realm of intelligent luminescent materials but face challenges from aggregation-caused quenching and/or amorphization during mechanical processing. Integrating aggregation-induced emission (AIE) luminogens into architecture highly crystalline metal-organic frameworks (MOFs) could potentially address these issues. In this work, two isomorphic Zn-MOFs ({[Zn(TCPE)0.5(Lx)0.5]·guests}n, where H4TCPE = 1,1,2,2-tetra(4-carboxylphenyl)ethylene, L1 triethylenediamine, and L2 piperazine) are synthesized via a multiligand assembly approach. The mechanochromic behaviors observed have been thoroughly analyzed, with focus on influence linker effects. Under grinding, lattice contraction is accompanied by distortion benzene rings within TCPE4-, leading to altered intramolecular twisted charge transfer Zn-MOFs, which subsequently changes their properties. potential application behavior light-emitting diodes was preliminarily explored.
