The invention relates to the use of a onium salt functionalized by at least one organic function, as a soluble support, in the presence of at least one organic solvent, for organic synthesis of a molecule, in a homogenous phase, by at least one transformation of said organic function. The onium salt enables the synthesized molecule to be released. The onium salt is present in liquid or solid form at room temperature and corresponds to formula A

Abstract To discover novel fluorophores of solution and solid dual-state emission (DSE) materials, unique V-shape furo[2,3-b]furans have been designed and synthesized by a one-pot method for the first time and their photoluminescent properties have been explored in benzene, THF, DMF and DMSO, as well as in the solid state. As the best example, 2,5-bis(4-(9H-carbazol-9-yl)phenyl)-6a-amino-3a,6a-dihydrofuro[2

Two new tetraphenylethene modified β-ketoiminate boron complexes (TTPE-H and TTPE-CN) have been rationally designed and successfully synthesized. The two D–π–A type compounds exhibit typical twisted intramolecular charge-transfer (TICT) emission and evident aggregation-inducedemission (AIE) characteristics, remarkable luminescence mechanochromism, and high solid state efficiency (up to 0.785 and 0
A new tetraphenylethene functionalized β-diketonate boron luminogen BF2-TPE has been designed and successfully synthesized, and its aggregation induced emission (AIE) characteristics and the mechanofluorochromic (MFC) behaviors have been investigated in detail. The results showed that boroncomplex BF2-TPE could emit intense yellow fluorescence in the solid state (λem = 544 nm, Φf = 92.5%) and exhibited
