Herein, we prepared two novel pairs of enantiomeric gold cluster complexes, AU4PL4/Au4PD4 and (Au4L4)n/(Au4D4)n with at. precision. In Au4PL4/Au4PD4, the discrete chiral Au4-based aggregation-induced emission (AIE) luminogens are separated by bulky substitutes. The corresponding aggregates are cyan-emitting with a photoluminescence quantum yield (PLQY) of 14.4%. Upon decreasing the size of the substituents, these chiral Au4 clusters are strung together by inter-cluster Au-Au interactions, which cause a low-energy green emission from the aggregated (Au4L4)n/(Au4D4)n with a much higher PLQY of 41.4% and more intense circularly polarised photoluminescence (CPL) with a dissymmetry factor |gPL| of 7.0 x 10-3. Using (Au4L4)n/(Au4D4)n, circularly polarised organic light-emitting diodes (CP-OLEDs) were for the first time fabricated. These findings signify that inter-cluster metallophilic interactions are a new and important type of driving force for AIE and crystallization-induced emission (CIE), suggesting great potential of CPL-active metal clusters in CP-OLEDs. In the experiment, the researchers used many compounds, for example, (S)-4-Isopropylthiazolidine-2-thione (cas: 76186-04-4COA of Formula: C6H11NS2).
(S)-4-Isopropylthiazolidine-2-thione (cas: 76186-04-4) belongs to thiazolidine derivatives. The thiazolidine ring is a cyclic N,S acetal, and most syntheses of perhydrothiazolo [3,2-a]pyridines construct the five-membered ring by condensation of aldehydes or ketones either as such or masked. Thiazolidine and its composites are key components of many natural products and drugs , and are also present in many synthetic compounds such as anticancer, anti-inflammatory, antitubercular, antifungal, antiviral, anti-HIV, cytotoxicity, antitrypanosomal, antinociceptive and anti-hypernociceptive compounds.COA of Formula: C6H11NS2
