Abstract

Tricoordinate boron with its vacant p-orbital is a potent �-acceptor in conjugated organic molecules relevant to the construction of novel optoelectronic materials. The new concept of kinetic stabilization by structural constraint offers a powerful strategy that enables the synthesis of hitherto unprecedented boron-containing polycyclic aromatic hydrocarbons. These new planarized organoboranes feature intriguing photophysical and self-assembly properties and hence are particularly interesting for application in organic optoelectronic devices.

Highlights

  • Owing to the increased environmental awareness and diminishing natural resources, the last decades have witnessed vigorous research activities in the field of energy-saving technologies with low environmental impact

  • The main reason is the ease of structural tuning by means of organic synthesis which allows for efficient tailoring of their photophysical properties, supramolecular behavior and of the resulting function

  • A pertinent example is the donor–π–acceptor type (D–π–A) organoborane 1 disclosed by Wang et al (Figure 1).[6]
