Background:

• Donor-acceptor-substituted polyfurans (PFu) are promising for advanced material applications.
• Optimizing (hyper)polarizabilities is crucial for tailoring PFu material properties.
• Existing simultaneous property optimization (POPT) methods have limitations.

Purpose of the Study:

• To optimize the (hyper)polarizabilities of donor-acceptor-substituted polyfuran (PFu) using an alternating property optimization (POPT) approach.
• To demonstrate the capability and accuracy of the alternating POPT method in designing systems with specific properties.
• To compare the efficiency of alternating POPT with simultaneous POPT for complex systems.

Main Methods:

• Alternating property optimization (POPT) was applied to donor-acceptor-substituted polyfuran systems.
• Specific monomers were selected for both alpha-zz-maximizing and alpha-zz-minimizing POPT.
• Computational time was compared between alternating and simultaneous POPT methods.

Main Results:

• The alternating POPT approach successfully optimized (hyper)polarizabilities in PFu systems.
• Clear and consistent patterns in selected monomers were observed, aiding future material design.
• Alternating POPT demonstrated superior reliability and efficiency compared to simultaneous POPT, especially for multi-directional growth.

Conclusions:

• The alternating POPT method is a validated and accurate tool for designing PFu-based materials with tailored properties.
• The identified monomer patterns offer valuable guidance for the rational design of novel PFu materials.
• Alternating POPT presents a more efficient and reliable computational strategy for complex material optimization.
