Synthesis and spectroscopic characterization on the tri-iodide charge transfer complex resulted from the interaction between morpholine as donor and iodine σ-acceptor

Charge-transfer (CT) complex formed between morpholine (Morp) as donor with iodine (I2) as acceptor has been studied spectrophotometrically. The synthesis and characterization of morpholine CT-complex of iodine, [(Morp) 2]I+·I3- was described. This complex is readily prepared from the reaction of Morp with I2 within CHCl3 solvent. IR spectra, UV–Vis techniques and elemental analyses (C, H and N), characterize the Morph charge-transfer complex. Benesi–Hildebrand and its modification methods were applied to the determination of association constant (K), molar extinction coefficient (ɛ).
