ResumoA new facet of an old theme! Dyed crystals of aromatic carboxylic acids, a common topic in the scientific literature 100 years ago, are rarely discussed today. These mixed crystals are now reintroduced as superior model systems for studying the host–guest interactions that are so important in MALDI mass spectrometry. Orientations for included dyes are determined through polarization spectroscopy. The role of charge transfer is indicated by the X‐ray structure of Malachite Green · hydrogen phthalate.
