Balancing the rigidity of a π-conjugated structure for strong emission and the flexibility of liquid crystals for self-assembly is the key to realizing highly emissive liquid crystals (HELCs). Here we show that (1) integrating organization-induced emission into dual mol. cooperatively-assembled liquid crystals, (2) amplifying mesogens, and (3) elongating the spacer linking the emitter and the mesogen create advanced materials with desired thermal-optical properties. Impressively, assembling the fluorescent acceptor Nile red into its host donor designed according to the aforementioned strategies results in a temperature-controlled Forster resonance energy transfer (FRET) system. Indeed, FRET exhibits strong S-curve dependence as temperature sweeps through the liquid crystal phase transformation. Such thermochromic materials, suitable for dynamic thermo-optical sensing and modulation, are anticipated to unlock new and smart approaches for controlling and directing light in stimuli-responsive devices. The results came from multiple reactions, including the reaction of 1,6-Dibromohexane(cas: 629-03-8Category: bromides-buliding-blocks)
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.Category: bromides-buliding-blocks
