✦ Synopsis

Abstract

Electron donor‐acceptor cyclophanes 1 and 2, consisting of pyrene as the donor component and 1,8;4,5‐naphthalenete‐tracarboxdiimide as the acceptor component fixed by methylene chains in parallel face‐to‐face orientations, have been synthesized. The structures, based on an X‐ray analysis of 1 and on spectroscopic properties, are discussed with reference to intramolecular charge‐transfer interactions and are compared to those of the related excimer models [3.3]‐ and [4.4]pyrenophanes 3 and 4.
