Abstract
Achieving polarization controllable multicolor CPL remains a significant challenge. In this study, we presented a method for fabricating dual CPL materials with controllable polarizations by doping achiral dyes with distinguishable emission wavelengths and different linear dichroism properties into cholesteric liquid crystals (CLCs). R/S-CLC-1 doped with green-emitting dye PTZ (positive dichroism, SF = 0.33) and red-emitting dye NP (negative dichroism, SF = −0.09) can emit green and red CPL with opposite polarizations (glum = +0.54/–0.52 at 550 nm and −0.35/+0.36 at 645 nm) simultaneously. Conversely, R/S-CLC-2 doped with PTZ and another red-emitting dye PP (positive dichroism, SF = +0.58) can emit green and red CPL in the same polarization (glum = +0.48/–0.43 at 550 nm and +0.68/–0.68 at 645 nm). This approach enables enhanced information encryption capacity and anticounterfeiting by allowing a single CLC pixel to simultaneously store data from two channels.
期刊介绍：
ACS Materials Letters is a journal that publishes high-quality and urgent papers at the forefront of fundamental and applied research in the field of materials science. It aims to bridge the gap between materials and other disciplines such as chemistry, engineering, and biology. The journal encourages multidisciplinary and innovative research that addresses global challenges. Papers submitted to ACS Materials Letters should clearly demonstrate the need for rapid disclosure of key results. The journal is interested in various areas including the design, synthesis, characterization, and evaluation of emerging materials, understanding the relationships between structure, property, and performance, as well as developing materials for applications in energy, environment, biomedical, electronics, and catalysis. The journal has a 2-year impact factor of 11.4 and is dedicated to publishing transformative materials research with fast processing times. The editors and staff of ACS Materials Letters actively participate in major scientific conferences and engage closely with readers and authors. The journal also maintains an active presence on social media to provide authors with greater visibility.
