Synergistic Dual-Modification Strategy of π-Conjugated Cations and Tetrahedra: Rational Design of Ultraviolet High-Birefringence Monofluorophosphates

Key Points

• The aim is to enhance birefringence in non-π-conjugated systems by modifying active units.
• Proposed a dual-modification strategy for birefringent active units.
• Focused on the synergistic effects of π-conjugated cations and tetrahedra.
• Evaluated the effectiveness of modifications in increasing anisotropy.
• The dual-modification successfully improved birefringence in tested materials.
• Demonstrated a significant increase in optical performance metrics.
• Outperformed traditional single-component modification strategies.
