Abstract
Porous frameworks that display dynamic responsiveness are of interest in the fields of smart materials, information technology, etc. In this work, a novel copper-based dynamic metal-organic framework [Cu3TTBPE6(H2O)2] (H4TTBPE = 1,1,2,2-tetrakis(4″-(1H-tetrazol-5-yl)-[1,1″-biphenyl]-4-yl)ethane), denoted as HNU-1, is reported which exhibits modulable photoelectromagnetic properties. Due to the synergetic effect of flexible tetraarylethylene-backboned ligands and diverse copper-tetrazole coordination chemistries, a complex 3D tunneling network is established in this MOF by the layer-by-layer staggered assembly of triplicate monolayers, showing a porosity of 59%. These features further make it possible to achieve dynamic transitions, in which the aggregate-state MOF can be transferred to different structural states by changing the chemical environment or upon heating while displaying sensitive responsiveness in terms of light absorption, photoluminescence, and magnetic properties.

Abstract
It remains a great challenge to design and synthesize organic luminescent molecules with strong emission in both dilute solution and aggregate state. Herein, an organic cage with dodecadansyl groups (D-RCC1) from an easy sulfonation reaction displays strong emissive behavior in dilute organic solution with a quantum yield of 42%. Moreover, D-RCC1 exhibits an ultrahigh quantum yield of 92% in the solid state, which is more than 3 times that of 27% for the model compound D-DEA. The results of the experiment and theoretical calculation show that the three-dimensional symmetrical skeleton of the organic cage anchored evenly by multiple dye molecules effectively satisfies both high local density and a symmetrical distribution of chromophores, which prevents the interaction of dye molecules and ensures that dye molecules have strong emission in both single-molecule and aggregate states.
