Cho, Hye Jin;Kim, Kyung-su;Kim, Hyunwoo;Kim, Taewoo;Malyutin, Andrey G.;Rees, Douglas C.;Yoo, Byung-Kuk;Song, Changsik research published 《 Microcrystal Electron Diffraction Elucidates Water-Specific Polymorphism-Induced Emission Enhancement of Bis-arylacylhydrazone》, the research content is summarized as follows. Aggregation-induced emission (AIE) phenomena have gained intense interest over the last decades because of its importance in solid-state emission. However, the elucidation of a working mechanism is difficult owing to the limited characterization methods on solid-state mols., further complicated if dynamic structural changes occur. Here, a series of bis-arylacylhydrazones (BAHs) were synthesized, for which their AIE properties are only turned on by the reversible adsorption of water mols. We used microcrystal electron diffraction (MicroED) to determine the mol. structures of two BAHs directly from bulk powders (without attempting to grow crystals) prepared in the absence or presence of water adsorption. This study reveals the unambiguous characterization of the dependence of crystal packing on the specific cocrystn. with hydrates. The structural anal. demonstrates that water mols. form strong hydrogen bonds with three neighboring BAH-1, resulting in the almost complete planarization and restriction of the intramol. rotation of the mol. MicroED plays an important role in providing a decisive clue for the reversible polymorphism changes induced by the adsorption of water mols., regulating emissive properties.
