(Hetero)arene-fused boroles: a broad spectrum of applications

Abstract

(Hetero)arene-fused boroles, ‘antiaromatic’ 2n-electron π-systems, more stable and more functionalizable than boroles, offer greater potential for a variety of applications.

Highly Emissive 9‐Borafluorene Derivatives: Synthesis, Photophysical Properties and Device Fabrication

“…Interestingly, the stability of these F Mes‐protected boroles was improved significantly and, at the same time, their low reduction potentials and pronounced antiaromaticity were maintained [34] . Dibenzoboroles, also widely known as 9‐borafluorenes, exhibit significantly enhanced stability because of their reduced antiaromatic character, due to the delocalisation of π electrons over the fused biphenylene backbone [35, 36] . Benefiting from their easy accessibility, 9‐borafluorenes have been explored as a platform for chemical sensors, [37] novel ring‐extension reactions [38–42] and small‐molecule activation [43] .…”

Synthetic Approaches to Triarylboranes from 1885 to 2020

“…Furthermore, their synthesis should be possible from all knownb oront rihalides. Recently,t he synthesis of triarylboranes from potassium aryltrifluoroborates [27][28][29][30][31] and boronic esters [32] was reported.W ed on ot discuss dibenzoboroles [33] or boron-containing polyaromatic hydrocarbons (B-PAHs) [34][35][36] in our review as both topics have been reviewed recently.…”

Celebrating Todd Marder: 65th Birthday and His Contributions to Inorganic Chemistry

“…Todd embraces diversity not only in his group members and numerous local and international collaborators, but also in his research interests [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. For over 30 years, a significant part of his research has focused on metal-catalyzed borylation reactions, metal boryl complexes, mechanisms of borylation and other catalytic reactions [ 1 , 2 , 3 , 4 , 5 , 6 ], and the development of diboron(4) compounds and their chemistry [ 7 , 8 , 9 ].…”

“…One of the diboron(4) compounds he developed in collaboration with Prof. N. C. Norman (Bristol University), namely B 2 neop 2 , is now available commercially world-wide and is produced in multi-ton quantities. He also works in the fields of conjugated organometallic [ 10 ], organoboron [ 11 , 12 , 13 , 14 , 15 , 16 ] and organic materials [ 17 , 18 , 19 ] for linear and nonlinear optics, 2-photon excited fluorescent cell imaging [ 15 ], DNA/RNA/protein sensing [ 16 ], and on crystal engineering using perfluoroarene-arene interactions [ 20 ], among other areas, often combining several areas of his research in a single project.…”
