Experimental Protocol: Resonant Two-Photon Synthesis of 1D Furan Nanothreads (FNT) from Hemp-Derived Precursors

Key Points

• The aim is to validate the capability of TPA to polymerize furan into nanothreads under specific conditions.
• Performed two-photon absorption experiments at λ = 450 nm.
• Maintained static pressure at 5 GPa during the process.
• Monitored the formation of crystallized nanothread structures.
• Confirmed successful polymerization of hemp-derived furan under study conditions.
• Identified the emergence of ordered crystalline structures through the determined 'seed' formation.
