Circularly polarized (CP) light is one type of polarized light that has two electric vectors with the same amplitude but perpendicular to each other, and has a phase difference of π/2. With its potential applications in 3D display , optical data storage , optical sensors, and encryptions . CP light has become a hot research topic and attracted lots of interest , especially in high-efficiency organic lightemitting diodes. The traditional way to generate CP light from non-polarized light is to use a linear polarizer and quarter-wave plate, which requires complex device architecture and causes brightness loss . Alternatively, another way to generate CP light is to employ chiral luminescent materials, which emit CP light directly and have been known as circularly polarized luminescence (CPL) materials . The development of CPL materials has led to a more convenient and cost-effective way of producing CP light with high efficiency. There are three types of CPL materials that have been successfully used in CP-OLEDs, which are chiral fluorescence , thermally activated delayed fluorescence (TADF) , and phosphorescence materials . Among these, circularly polarized TADF (CP-TADF) materials are the most popular due to their high exciton utilization, photoluminescence quantum yields (PLQYs), and adjustable emissions. However, most of the CP-TADF molecules that have been reported to date have blue to green emission. There is a need for deep-red/near-infrared CPLactive emitters suitable for CP-OLED manufacturing.
