چکیده انگلیسی
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 7,7′,8,8′-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 (ɛ).
