With the rapid development on 3D printing technol., more and more works have been devoted to 3D display. 3D display will really come true by using circularly polarized luminescence (CPL)-active materials with both high quantum yield and dissymmetry factor (gem) in organic light-emitting diode OLED or liquid crystals (LCs). But so far most of these CPL materials cannot meet the real application requirement because of the low gem values in the range of 10-5-10-2. In this paper, ternary chiral emissive LCs (P-N*-LCs) is designed by doping chiral binaphthyl-based enantiomers as chiral dopant I (Guest 1) and achiral conjugated polymer as induced CPL emitter II (Guest 2) into nematic liquid crystal (N-LCs) Host 5CB. Both Guest 1 and Guest 2 show excellent compatibility with Host 5CB. The obtained ternary P-N*-LCs can emit strong-induced CPL signal with gem up to 1.12 and ΦFL up to 66.1%. This work first develops a new strategy for the smart design of excellent CPL materials from versatile achiral conjugation fluorescence polymers. In the experiment, the researchers used many compounds, for example, 1,6-Dibromohexane(cas: 629-03-8SDS of cas: 629-03-8)
1,6-Dibromohexane(cas: 629-03-8) is generally used to introduce C6 spacer in the molecular architecture. Some of the examples are: synthesis of pyrrolo-tetrathiafulvalene molecular bridge (6PTTF6) to study redox switching behavior of single molecules; synthesis of water-soluble thermoresponsive polylactides.SDS of cas: 629-03-8
