Circularly polarized organic light-emitting diodes (CP-OLEDs) and CP photodetectors have received enormous attention owing to their promising potential in light-related technologies. The simultaneous construction of efficient CP-OLEDs using the multifunctionality same chiral material remains be explored. Herein, achiral conjugated polymer poly(9,9-dioctylfluorene) (PFO) is used for coassembly with helical polyacetylenes. resulting emitters can achieve high-performance circularly electroluminescence (CPEL) a large dissymmetry factor (gEL) 0.11 high brightness 9035 cd m-2. By introducing flexible substrate into device, are realized. Additionally, such serve as photoactive layer photodetector detect light, maximum photocurrent (gph) order 10-1. This work provides route realize factors polyfluorene polymer, facilitating comprehensive versatile development.
