Malonate Crown Ethers as Building Blocks for Novel D-π-A Chromophores
摘要:
[GRAPHICS]A series of new crown ethers, Incorporating a malonate ester functionality, have been synthesized and derivatized with pi-electron rich aldehydes; to give, conjugated, extended "push-pull" compounds. Their ability to bind Lewis acid-like metal cations, such as Mg2+ and Eu3+, has been characterized, and the relative stability constants are presented. When the metal cation is bound to the malonate moiety within the crown ether cavity, the D-pi-A character of the molecular structure is greatly enhanced.
In this paper we describe the synthesis and intercomparison of several new methanofullerenes, each bearing a macrocyclic crown ether containing a malonate moiety directly attached to the C60-fullerene core. Their complexing abilities with primary alkylammonium ions were investigated by NMR and mass spectrometry, and also by transport experiments through a liquid membrane. We also report on their electrochemical
