9,10-Dihydro-9,10-diboraanthracene: Supramolecular Structure and Use as a Building Block for Luminescent Conjugated Polymers

摘要

The use of organoboranes in preparative chemistry has been established for decades.In contrast, research on boron-containing materials is still at an early stage, but numerous exciting perspectives are already emerging. The incorporation of boron into conjugated π systems leads to similar electronic states as oxidative doping but gives neutral materials because of the isoelectronic relationship between three-coordinate boron atoms and carbocations. Moreover, the ability of boron atoms to form Lewis acid-base pairs and thereby to disrupt the π-conjugation pathway can be exploited for the development of molecular switches because adduct formation is reversible in many cases.
