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^+ · i^- 3 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 (ε).
