Intramolecular electron donor-acceptor interactions / [3.3]- and [4.4]Cyclophanes of pyrene and 1,4;5,8-naphthalenetetracarboxdiimide / Charge transfer / Through-space interactions / UV/Vis spectroscopy
要旨:
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.
