Truxene: a promising scaffold for future materials

Abstract

Truxene (10,15-dihydro-5H-diindeno[1,2-a;1′,2′-c]fluorene), which is a heptacyclic polyarene structure, has attracted a great deal of interest due to its exceptional solubility, high thermal stability and ease with which it may be modified. Over the years and thanks to the advances in the synthesis of truxene derivatives, the scope of applications of this attractive building block, initially limited to synthesis and photoluminescence, has nowadays been extended to organic electronics. This review aims at highlighting the benefits brought by the introduction of this rigid star-shaped molecule in different materials. Perspectives for this highly appealing molecule in future research will also be put forth.
