Two pyrene-imidazole-based structural isomers, axisymmetric syn-PyDTI and centrosymmetric anti-PyDTI, have been easily produced and successfully separated in a one-pot reaction. Crystalline syn-PyDTI exhibited a 2-fold higher quantum efficiency than anti-PyDTI and displayed a much better performance in OLEDs with a ηc.max of 11.4 cd A-1 (8.8 cd A-1 for anti-PyDTI), although they possess the same apparent electronic structure. Observations revealed that the molecular excited-state properties are derived from distinct structural symmetries.

In this paper, a simple strategy to change the emission behaviour of luminogenic materials was developed. Tetraphenylethene (TPE)-functionalised benzothiazolium salts with different counteranions (TPEBe-X; X=I-, ClO4- and PF6-) were designed and synthesised. All the luminogens show weak red emission in the solution state that originates from intramolecular charge transfer from TPE to the benzothiazolium unit. Whereas aggregate formation enhances the light emission of TPEBe-ClO4 and TPEBe-PF6, that of TPEBe-I is quenched, thus demonstrating the phenomena of aggregation-induced emission and aggregation-caused quenching. TPEBe-I works as a light-up fluorescent sensor for Hg2+ in aqueous solution with high sensitivity and specificity owing to the elimination of the emission quenching effect of the iodide ion by the formation of HgI2 as well as the induction in aggregate formation by the complexation of Hg2+ with the S atom of the benzothiazolium unit of TPEBe-I. A solid film of TPEBe-I was prepared that can monitor the level of Hg2+ in aqueous solution with a detection limit of 1 μM. From darkness to light! A series of tetraphenylethene-functionalised benzothiazolium salts with different counteranions (TPEBe-X) was developed. By varying the counteranion from I- to ClO4- or PF 6-, TPEBe-X changes its emission behaviour from aggregation-caused quenching to aggregationinduced emission (see figure). TPEBE-I shows a light-up response to Hg2+. Copyright
