Polymorphism-dependent emissions of two phenoxazine derivatives

Two phenoxazine derivatives 1 and 2 were synthesized and their photoluminescent properties were systematically investigated. These two compounds presented crystallization-induced emission (CIE) with polymorphism-dependent emission (PDE). Compound 1 presented two single crystal structures with maximum.emission wavelengths of 540 nm and 560 nm, while compound 2 possessed three single crystal structures with.maximum emission wavelengths of 516 nm, 547 nm, and 556 nm, respectively. Moreover, compound 1 showed.reversible mechanochromic luminescence by grinding/heating or solvent fuming processes.
