Gamidi Rama Krishna, Mangalampalli S. R. N. Kiran, Cassandra L. Fraser, Upadrasta Ramamurty and Chilla Malla Reddy The Relationship of Solid-State Plasticity to Mechanochromic Luminescence in Difluoroboron Avobenzone Polymorphs Advanced Functional Materials 23
Quantification of mechanical properties using a nanoindentation technique in a polymorphic, mechanochromic luminescent (ML) material allows a structure-mechanical response in the stiff and soft forms to be established. This explains the quick recovery and a very prominent reversible ML behavior of the two forms. The structural analysis suggests that the introduction of slip planes in crystals is the key to achieving an efficient ML property in fluorophores or a soft nature in organic functional materials.
