Iridaaromatics via Methoxy(alkenyl)carbeneiridium Complexes

Abstract

This review describes the development of a versatile methodology to synthesize polycyclic metallaaromatic hydrocarbons based on iridium, as well as the studies that helped us to determine and understand what is required in order to broaden the scope and the selectivity of the methodology and stabilize the complexes obtained. This methodology aims to open the door to new materials based on graphene fragments.

Optical and electrochemical properties of spirobifluorene iridanaphthalene complexes

“…In the last decade, the chemistry of metallaaromatic compounds has grown extensively, and new structures are known, including those in which the substitution of a carbon atom by a transition metal transforms a non-aromatic organic compound into an aromatic one. [1][2][3][4][5][6] The interest in the metallaaromatic compounds is not only focused on their aromatic and organometallic reactivity but also on the study of their optical, electronic and thermal properties with a view to their application in molecular materials and devices. [7][8][9][10][11][12][13] Besides, organic molecules with a non-centrosymmetric electronic structure, high thermal and morphological stability and charge transfer capacity, such as allenes or spirobifluorene derivatives have taken attention in recent years.…”

Radical metallacyclopropene: synthesis, structure and aromaticity

“…With metal involved in the delocalized structures, metallaaromatics are generated, showing diverse and interesting aromatic properties. [2][3][4][5][6][7] Both 2D and 3D radical aromatics have been demonstrated in the last decade. 8,9 In metallaaromatics, the metal center could have various oxidation states with the maintenance of a delocalized structure.…”

“…8,9 In metallaaromatics, the metal center could have various oxidation states with the maintenance of a delocalized structure. [2][3][4][5][6][7] However, radical metallaaromatics are rare. To our knowledge, spiro metalloles reported by Xi and coworkers in 2021 were limited examples of metallaaromatics containing radical metal centers (Fig.…”
