EDA COMPLEXES OF 9-SUBSTITUTED ANTHRACENES WITH TCNQ SUMMARY Key words : Electron donor acceptor complexes, 9-Substituted Anthracenes, TCNQ The purpose of this study is to examine how to affect the charge transfer complexes of substitued groups on the anthracene ring. Electron donor acceptor complexes of anthracene and 9-Substituted anthracenes as electron donors with TCNQ ( 7,7,8,8- Tetracyanoquinodimethane) as a electron acceptor have been examined by spectrophotometric method. Stoıchıometnes of the complexes were calculated by Jop's method. Equilibrium contstants of the complexes were calculated by Benesi- Hildebrand equation. Thermodynamic contstants of the complexes were calculated by Van't Hoff equation. EDA complex of Anthracene-TCNQ gave a maxsimum absorption at 760 nm. Stoıchıometry of complex is 1:1. Equilibrium contstant of complexe is 1,69 Lmole“1. Thermodynamic contstants are AH : -9,287 kcal. mole”1 and AS : -7,824cal.K“1. mole”1. EDA complex of 9-Bromoanthracene-TCNQ gave a maxsimum absorption at 744 nm. Stoıchıometry of complex is 1:1. Equilibrium contstant of complex is 1,31 Lmole^.Thermodynamic contstants are AH : -18,427 kcal.mofe“1 and AS : -11,042 caLK”1. mole“1. EDA complex of 9-Methylanthracene-TCNQ gave a maxsimum absorption at 755 nm. Stoıchıometry of complex is 1:1. Equilibrium contstant of complex is 3,14 Lmole”1.
