Nucleotide-Based White Circularly Polarized Luminescence Materials in Lanthanide Deep Eutectic Solvents

The self-assembly of nucleotides into sophisticated biomolecular architectures offers a powerful platform for developing advanced functional materials. Herein, we exploit the innate chirality and metal-coordination capability of nucleotides to fabricate biomolecular coordination polymers with circularly polarized luminescence (CPL). By integrating nucleotides (AMP, GMP, UMP, CMP) with lanthanide-based deep eutectic solvents (DESs) that serve as both a reactive medium and a source of red and green emission, we successfully constructed nucleotide-lanthanide coordination polymers. These biomolecular complexes not only exhibited characteristic lanthanide emissions but also demonstrated significant CPL activity. Remarkably, a white-light-emitting coordination polymer with white circularly polarized luminescence (W-CPL) was achieved by incorporating blue-emitting carbon dots into the AMP-coordinated system, forming a solvent-free supramolecular assembly. Furthermore, a prototype light-emitting diode (LED) device was fabricated by coating these nucleotide-based complexes onto a UV chip, successfully generating electrically driven polarized visible light. This work underscores the immense potential of nucleotide biomolecules as versatile scaffolds for crafting next-generation polarized optical materials and devices.
