Spectroscopic and thermal studies on the charge transfer complexes formed between morpholine as donor with ρ-chloranil and 7, 7', 8, 8'-tetracyanoquinodimethane

Abstract EN

Charge-transfer (CT) complexes formed between morpholine (Morp) as donor with CHL and TCNQ as acceptors have been studied spectrophotometrically.

The synthesis and characterization of morpholine CT-complexes of p-chloranil, [(Morp)(CHL)] and 7,70,8,80-tetracyanoquinodimethane, [(Morp)(TCNQ)] were described.

These complexes are readily prepared from the reaction of Morp with CHL and TCNQ within CHCl3 and/or MeOH solvents.

IR, UV–Vis techniques, elemental (C, H, and N) and thermal analyses (TG / DTG) characterize the two Morp charge-transfer complexes.

Benesi-Hildebrand and its modification methods were applied to the determination of association constant (K), and molar extinction coefficient (e).
