Abstract
4′-Octadecanoylbenzo-15-crown-5 (I) and four 4′-alkylbenzo-15-crown-5 ligands [4′-XB15C5 where X =n-C18H37 (II), X =n-C16H33 (III), X =n-C14H29 (IV), and X =n-C12H25 (V)] have been synthesized. The π-A isotherms ofI andII were systematically investigated. The results indicated that the Langmuir-Blodgett (LB) films have high stability where the ratios ofI/SA andII/SA were 1 : 1 and 1 : 10, respectively, with a 6.2 pH subphase. The LB films of the crown ethers were deposited onto graphite electrodes pretreated by immersing them in liquid wax. The peak current reached the maximum value when the electrode surface was modified with five layers of the amphiphilic crown ethers.
