✦ Synopsis

The electron donor acceptor complexes of iodine with phospholipids such as phosphatidylethanolamine (PE), lysophosphatidylcholine ILPC) and sphingomyelin (SM) have been studied spectrophotometrically in cyclohexane solution as well as in solid film. From the results, the electron donating properties of phospholipids towards iodine have been compared including the earlier results of iodine complex with phosphatidylcholine (PC). Thus the electron donor strengths of the phospholipids studied are in the order: SM > PC > LPC > PE. The calculated ionization potentials of phospholipids from the charge-transfer bands are in the range 6.72-6.79 eV.
