A novel rhodamine-pyridine conjugated spectroscopic probe RhP (I) was synthesized and its x-ray single crystalline properties were revealed with tabulation. The RhP displayed a distinct pale-pink colorimetric and “”turn-on”” fluorescent response to Fe3+ in aqueous media [H2O:DMSO (95:5, volume/volume)] than that of other interfering ions. During the Fe3+ recognition, the absorption (UV-visible) and photoluminescence (PL) spectral studies revealed new peaks at 561 and 592 nm, resp. The 1:1 stoichiometry and binding sites were verified by Job′s plot, ESI-mass, and 1H NMR titrations Subsequently, LOD and binding constant for RhP + Fe3+ complex were estimated as 102.3 nM and 6.265 × 104 M-1 from linear fitting and Benesi-Hildebrand plots, correspondingly. Sensor reversibility of RhP + Fe3+ by EDTA was demonstrated by UV/PL and TRPL studies. Moreover, the photoinduced energy transfer mechanism and band gap changes were established from the DFT interrogations. Lastly, cellular imaging studies were carried out to authenticate the real applicability of RhP in Fe3+ detection.
