This study investigates the creation and analysis of six novel dansyl derivatives (named L1 to L6) their incorporation into PMMA polymers for environmental sensing purposes. The properties these were extensively examined in different solvents solid states. Notably, they exhibited a significant change color depending on solvent's polarity, suggesting potential assessing microenvironmental polarity. Moreover, showed promising capabilities selectively detecting Cu2+ Hg2+ metal ions acetonitrile solution, forming individual species with metals. Furthermore, responsiveness changes acidity basicity was explored both solution within polymer matrix, indicating pH-sensitive applications. By integrating polymers, acid-base sensitive materials produced, suitable monitoring conditions such as hazardous gas detection pH level changes. integration addresses solubility challenges compounds broadens use various
