Polymorphism in organic compounds is a fascinating phenomenon with diverse applications. Rational development of polymorphic forms challenging and demands more investigations. Subtle variations functional groups can lead to variation intra- as well intermolecular interactions promote polymorphism.

Abstract There is a notable shift toward organic functional materials for their advantages in terms of availability, processability and biodegradability. Solid‐state emitters, though rare, are fascinating with diverse range applications. In this work we utilize crystal engineering principles to design Schiff bases 1 2 , realize solid state emission its tuning. The products have been characterized studied through crystallographic, Hirshfeld, optical studies. Structural studies validate crystallization molecule methanol water, respectively, packing predominantly aided by solvent assisted hydrogen bonding, while the π‐π stacking interactions absent.
