Flexible molecular tweezer based on a dioxa[2.2]orthocyclophane linked with weak electron acceptor
A flexible receptor having three aromatic chromophores can bind a weak electron acceptor which is linked covalently to the receptor with an appropriate alkyl chain. The receptor has tweezer type conformation when the acceptor was entrapped within its cavity. Sandwich type donor-acceptor-acceptor arrangement was realized in solution.
