The intromolecular charge transfer spectra of six crown ethers, namely 15C5, B15C5, 18C6, B18C6, DB18C6 and DC18C6 acting as donors, and iodine, acting as an acceptor, were studied in the UV-vis region in methylene chloride. The complex formation constants were computed. The results indicate that bo
A spectrophotometrtc study was made of the formatron of charge-transfer complexes between benzo-18crown-6 ether and some x-acceptors ur methylene chlorrde at 25Β°C The spectroscoptc data mdtcate that the PhG-CHr-CH,-group IS responsible for the complexatron wrth n-acceptors The benzo-18crown-6 ether-
