Emissive nanoclusters in B4 helical nanofilaments for the next generation of polarized optics

POSTER

Abstract

The purpose of this study is to maximize circularly polarized luminescence with irradiated light utilizing chiral templating that manipulates the helical nature of bent core liquid crystals concentrated with a high quantum-yield dye. Using this new, all-inclusive model in lab, a polarized light source and control through the helical-type morphology of the template gives access to highly tunable circularly polarized light with excellent dissymmetry factor () enclosed within its own system which can aid in many optical processes or thermal-rate indicators. Using a chiral template and an achiral dye with excellent quantum yield, chirality can be transferred, thus resulting in a complex that can induce circular polarization without losing intensity through aggregation-caused quenching. Using Polarized Optical Microscopy and Circularly Polarized Luminescence instrumentation while fine tuning the weight concentrations of the Clustomesogen, confined within a variety of alignment layers within quartz cells, the luminescence dissymmetry factor of 0.55 was obtained with the maximum concentration of weight being 50%. To further strengthen the data for thermal applications, Differential Scanning Calorimetry data was collected and will lend information regarding helpful phase changes in these systems.
