Specifications

Luminescence dissymmetry factor (|g_lum|)

{'zh': '0.25', 'en': '0.25'}

Advantages

Facile synthesis

The CPL-active molecules are obtained by a facile method, avoiding complex multi-step synthesis.

High g_lum

The maximal |g_lum| reaches ca. 0.25 in spin-coated and annealed films, which is high for organic systems.

Tunable CPL

The CPL effect can be controlled by manipulating aggregate behavior in films, e.g., by spin-coating and annealing.

Applications

• OLED displays：Emit circularly polarized light directly in OLEDs, simplifying device architecture and reducing energy loss.
• circularly polarized light detection：Serve as active materials for detecting circularly polarized light with handedness discrimination.
• anti-counterfeiting labels：Fabricate anti-counterfeiting labels that require specialized CPL detection for authentication.
