Unique piezochromic fluorescence behavior of organic crystal of carbazole-substituted CNDSB†
Abstract
CzCNDSB with a highly twisted conformation in the solid state is constructed. Single crystal measurements prove that it possesses an inside pore with a diameter of 8 Å and further forms a long-range orderly arrayed channel. CzCNDSB can sense external pressure from 1.0 atm to 9.21 GPa, accompanied by color changes from green to red with excellent reversibility and reproducibility.
