We describe the growth and spectroscopy of well-defined mixed crystals of KH2PO4 (KDP) containing both natural and synthetic organic dyes in the {010} and {101} growth sectors. Our summary reevaluates historical dye inclusions, reveals others discovered in a directed screening, and ultimately describes dyes rationally synthesized for the recognition of KDP surfaces. Absorption and emission spectroscopies with polarized light are used to characterize these mixed crystals. A model that accounts for the facial selectivity of the dyes is proposed. We show that a chiral chromophore is selective enough to distinguish enantiomorphous faces of KDP. Tailor-made dye inclusions in KDP suggest the possibility of developing new photonic materials by coupling the optical properties of the host and guest.
