Abstract:
The strong donor properties of tetrakis dimethylamino ethylene MAE are determined by its interactions with pi acceptors. Colors of n-hexane solutions of this donor with pyrene, anthracene, and perylene are ascribed to intermolecular charge-transfer transitions, where the hydrocarbons function as electron acceptors. Azahydrocarbons similarly produce colors and are stronger acceptors. All association constants for complex formation ith the tetraaminoethylene are close t6 zero and this is ascribed to the bulk of the TMAE molecule, and all colors may be made to disappear in the frozen solutions or in the frozen, pure materials. These results and experimental evidence from other sources are correlated with a proposed electronic structure of TMAE. A consideration of the factors that stabilize acceptor-donor complexes, is used to reinterpret an earlier proposal that such an interaction occurs between the methylbenzenes and anthracene. Author
