Grinding size-dependent mechanoresponsive luminescent Cd(ii) coordination polymer†
Abstract
In this work, we report a new mechanoresponsive luminescent Cd(II) coordination polymer that exhibits a sensitivity to mechanical stimulation. The luminescence colour changed gradually from weak yellowish-green to bright cyan in response to different grinding sizes, thereby showing interesting mechanochromic properties, namely a grinding-enhanced luminescence and good crystalline maintenance ability.
