Micro-nano-level photonic waveguide regulation is essential for future on-chip photonic integrated systems and is still of great challenges. We report a molecular design strategy, changing the position of the methyl substituent makes the arrangement of the three isomer molecules different in their respective crystals. Based on this strategy, three sheet-like crystals with different polygonal morphologies were prepared via solution self-assembly approach. The in-depth optical measurements demonstrated that these three microsheet crystals have different 2D optical waveguide performances related to the shapes. Our work provides a feasible design strategy and material preparation method for realizing precise 2D optical waveguide modulation, which lays the foundation for complex photonic integrated systems in the future.
