dc.description.abstract	The (13E,19E)-N1′,N3′-bis[4-(diethylamino)-2-hydroxybenzylidene]malonohydrazide (L) has been developed for the detection of Th4+ ions using dual channel signalling system. The UV–vis absorbance and fluorescence spectroscopic data revealed the formation of L–Th4+ complex in 1:1 equilibrium. The density functional theory (DFT) also confirms the optimum binding cavity for the recognition of metal ion. The binding constant computed from different mathematical models for an assembly of L–Th4+. The detection limit of L for Th4+ recognition is to a concentration down to 0.1 μM (0.023 μg g−1). The present sensing system is also successfully applied for the detection of Th4+ ion present in soil near nuclear atomic plants.	en_US
