On February 28, 2019, Chen, Yiyang; Peng, Zhixing; Tao, Yuhan; Wang, Zaibin; Lu, Ping; Wang, Yanguang published an article.Formula: C12H8N2 The title of the article was Polymorphism-dependent emissions of two phenoxazine derivatives. And the article contained the following:
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, resp. Moreover, compound 1 showed reversible mechanochromic luminescence by grinding/heating or solvent fuming processes. The experimental process involved the reaction of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile(cas: 2510-01-2).Formula: C12H8N2
