Controlling the spectral and polarization response of two-dimensional (2D) crystals is vital for developing ultrathin platforms compact optoelectronic devices. However, independently tuning optical anisotropy remains challenging in conventional semiconductors due to intertwined nature their lattice electronic structures. Here, we report spectra-orthogonal anisotropy─where tuned response─in wafer-scale, one-atom-thick 2D molecular crystal (2DMC) monolayers synthesized on monolayer transition-metal dichalcogenide (TMD) crystals. Utilizing concomitant consistency structural tunability perylene derivatives, demonstrate tunable 2DMCs with similar profiles, as confirmed by room-temperature scanning tunneling microscopy cross-polarized reflectance microscopy. Additional angle-dependent analysis single-crystal polycrystalline domains reveals an epitaxial relationship between 2DMC TMD. Our results establish a scalable, molecule-based crystalline platform unique functionalities unattainable covalent solids.
