Abstract
A new family of mono-substituted polyacetylene having a highly bulky substituents was synthesized and characterized. The polymerization of 17α-ethynylestradiol (EED) was performed by various transition metal catalysts to give the resulting polymer in moderate yield. The polymer structure was characterized by various instrumental methods to have a conjugated polymer backbone system having the designed substituent. This polymer was completely soluble in organic solvents. The electro-optical and electrochemical properties of poly(EED) were measured and discussed. This exhibited the reversible electrochemical behaviors between the doping and undoping peaks. The HOMO energy level calculated from electrochemical measurements was 5.47 eV.
