Redox-Induced Transformation from an Extended to a pi-Stacked Conformer in Acyclic Bis(catecholacetal)s of Acetylacetone

摘要

The design and synthesis of new pi-stacked molecular arrays holds potential for the preparation of wirelike materials for applications in the e~er-evolving area of molecular electronics and nanotechnology.We have recently demonstrated that polyfluorenes adopt cyclophane-like pi-stacked structures when woven at the alternating carbon atoms of the backbone of an acyclic alkane(Figure I).
