Abstract

Synthesis of L1–L3, their thorough characterization by spectral as well as structural studies and use in selective photochemical detection of Fe³⁺ and Hg²⁺ at ppb level have been described. Notably, these exhibit bifunctional behaviour toward Fe³⁺ (CHEF) and Hg²⁺ (chemodosimetric) which has been unequivocally established by various studies.
