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. Crystalline solids emissive: ( λ max 474 nm, τ 0.35 ± 0.04 ns) (481 1.80 0.07 aggregation induced (AIE) active. Mechano thermo‐fluorochromic responses attributed phase changes triggered grinding desolvation, respectively. nonemissive solutions detect presence Pb(II) /Hg(II) turn‐on, limit detection (LOD) values 0.0017–0.0022 ppb, picric acid sensing reported AIE luminogen (AIEgen) forms LOD 0.0017 ppb 0.0034
