Abstract Supramolecular chemistry provides a versatile approach to tune organic solid state luminescence by controlling the molecular organization through weak interactions. In this study, we have successfully tuned the solid state luminescence of 2‐cyano‐3(4‐(diphenylamino)phenyl)acrylic acid (CDPA) by co‐crystallizing with substituted pyridines. The position of methyl group on the pyridine (4‐picoline, 3‐picoline, and 2‐picoline) has a dramatic effect on the supramolecular interactions formed, from usual carboxylic acid–pyridine interactions to deprotonation of CDPA in the crystal lattice and that allows to tune the CDPA solid state luminescence from 587 to 548 nm gradually.
