Photomechanochromic vs. mechanochromic fluorescence of a unichromophoric bimodal molecular solid: multicolour fluorescence patterning

“…S8 †. Although several multistimuli, multiresponsive, and multicolour luminescent molecular solids have been reported,11,15,17,26,27 those that allow one to perform mask-/template-free fluorescence patterning with three or more colours are rare,17,27 because it requires selective or orthogonal responses to external stimuli such that the later stimuli would not overwrite the colour of the earlier created patterns. The five-colour pattern shown in Fig.…”

“…Compound 1 was originally designed to investigate the scope of multicolour mechanochromic14,15 and vapochromic16 photoluminescence in line with our recently reported examples,17,18 in which the nonplanar cogwheel-shaped pentiptycene group19 facilitates the manipulation of intermolecular π–π interactions and thus the luminescence colours via external mechanical stresses and/or vapour deposition. To our surprise, 1 displays not only intriguing mechanofluorochromism (MFC) and vapofluorochromism (VFC) that lead to multicolour fluorescence including white-light emission but also unprecedented bimodal multicolour PMFC that originated from the [4 + 4] photodimerization of the anthracene moiety (Fig.…”

High-pressure sapphire capillary cell for synchrotron single-crystal X-ray diffraction measurements to 1500 bar

“…'Soft' crystals undergo structural transformations under applied pressure to form novel phases with unique properties (Horike et al, 2009;Kato et al, 2019). The ability to control the structure and properties of single crystals with pressure benefits numerous technological and industrial applications, including sensors (Giachino, 1975), switches (Woodall et al, 2014;Ma et al, 2016) and storage materials (Graham et al, 2011(Graham et al, , 2012, and can also be used to derive fundamental structure-property relationships required to develop crystals with predictable pressure responses.…”

Ca-MOF-Derived Porous Sorbents for High-Yield Solar-Driven Atmosphere Water Harvesting

“…The Raman spectrum of PCC-42 shows broad bands at 1351 and 1565 cm −1 , which are attributed to the D and G bands of the porous carbon (Figure S3). 37 Other samples were synthesized under different conditions for comparison, and the SEM images are shown in Figures S4− S6. When the pyrolysis temperature was increased to 500 °C and held for different times, the diffraction peaks of CaCO 3 gradually increased (Figure S7a, PDF: 47-1743).…”
