Abstract

Chemistry Chemistry, Multidisciplinary Physical Sciences Science & Technology
Tetraphenylethene (TPE) substituted pyrazabole 2 was designed and synthesized by the Pd-catalyzed Suzuki cross-coupling reaction. The pyrazabole exhibits strong aggregation induced emission (AIE) and reversible mechanochromic behavior with high color contrast between blue and green. The powder XRD studies show that destruction of crystalline state into amorphous state is responsible for mechanochromism.
