Piezochromic Luminescence of Donor–Acceptor Cocrystals: Distinct Responses to Anisotropic Grinding and Isotropic Compression
Yingjie Liu, Qingxin Zeng, Bo Zou, Yu Liu, Bin Xu, Wenjing Tian
The distinct luminescent responses arising from anisotropic grinding and isotropic compression of a donor–acceptor co‐crystal are demonstrated by B. Zou, B. Xu et al. in their Communication on page 15670 ff. The results indicate that the hypochromatic shifted emission under grinding is attributable to a unique structural reorganization from a loosely segregated‐stack to a mixed‐stack, while the bathochromatic shifted emission under compression originates from the closer proximity to the formation of the tight‐packing structure.
