Abstract

Abstract: The effect of donor (D)–acceptor (A) alignment on the materials electronic structure was probed for the first time using novel purely organic porous crystalline materials with covalently bound two‐ and three‐dimensional acceptors. The first studies towards estimation of charge transfer rates as a function of acceptor stacking are in line with the experimentally observed drastic, eight‐fold conductivity enhancement. The first evaluation of redox behavior of buckyball‐ or tetracyanoquinodimethane‐integrated crystalline was conducted. In parallel with tailoring the D‐A alignment responsible for "static" changes in materials properties, an external stimulus was applied for "dynamic" control of the electronic profiles. Overall, the presented D–A strategic design, with stimuli‐controlled electronic behavior, redox activity, and modularity could be used as a blueprint for the development of electroactive and conductive multidimensional and multifunctional crystalline porous materials. Abstract : Ein Ausflug ins Unbekannte kann unerwartete Entdeckungen hervorbringen. So erging es Elektronenakzeptoren, die sich in unerforschtes Gebiet kovalenter organischer Gerüste begeben haben. Statt sich zu verirren, zeigten die akzeptorbasierten (rein organischen) porösen COF nicht nur eine erhöhte Leitfähigkeit, sondern behielten auch ihre redoxaktive Natur bei.
