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]
Summary
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 new concept of kinetic stabilization by structural constraint offers a powerful strategy that enables the synthesis of hitherto unprecedented boron-containing polycyclic aromatic hydrocarbons.
