Fluorescent probe IP has been synthesized to investigate the phenomenon of Fe3+ acquisition and accumulation in different parts of Hygrophila Spinosa by enhancement of photoluminescence. [Display omitted] •Rhodamine pyrene conjugate (IP) has been employed for selective estimation of Fe3+.•Investigation of accumulation of Fe3+ in Hygrophila spinosa by chemosensing method.•Visualization of Fe3+ in different parts of H. spinosa through fluorescence microscopy.•Spectroscopic and theoretical analysis were done to establish IP-Fe3+ interaction. Rhodamine functionalized fluorescent probe IP has been synthesized to investigate the phenomenon of Fe3+ acquisition and accumulation in Hygrophila spinosa. H. spinosa is a tropical medicinal plant which is iron rich and consumed for the treatment of the patients suffering from anaemia. IP is capable of selectively binding Fe3+ by enhancing fluorescent intensity via “turn on” mechanism due to complex formation. Spectroscopic studies and microscopic tools helped in better understanding about the acquisition as well as the quantitative accumulation of Fe3+ in different parts of the plant.
