Two new coordination polymers {[Zn(L)(dma)] 2 · H 2 O} n ( 1 ) and {[Cd(L)(H 2 O) 3 ] · dma · H 2 O} n ( 2 ) {H 2 L = 5‐[(pyren‐9‐ylmethyl)amino]isophthalic acid, dma = N , N ‐dimethylacetamide} were synthesized by the reaction of H 2 L and zinc(II) or cadmium(II) nitrate in mixed solvents. Single‐crystal XRD analyses show that polymers 1 and 2 have 1D chain structures. Due to the existence of π ··· π stacking interactions in the crystal structure, 1 exhibits mechanoresponsive luminescence, and the fluorescence color changes from weakly yellow to noticeably greenish yellow after application of external mechanical stimulus. Compound 1 shows grinding‐size‐dependent fluorescent emission.
