“…The aim of the synthesis was similar—obtaining the most efficient materials for OLEDs or molecules that will be used in further functionalization. Liheng Feng et al presented two 1,6-disubstituted pyrenes containing 4-(5-phenyl-1,3,4-oxadiazol-2-yl)phenyl 29 and 9-benzyl-9 H -carbazol-2-yl 30 groups and described by them as pyrenes substituted at positions 2 and 7 (Scheme 16) [51]. The catalytic system [Pd(PPh 3 ) 4 ]/K 2 CO 3 in DMSO/H 2 O was used, which resulted in the products 29 and 30 with yields of 65% and 56%, respectively.…”

Disubstituted pyrenes at the non-K region by the same or different (hetero)aryl groups have proven to be an increasingly interesting area of research for scientists over the last decade due to their optical and photophysical properties. However, in this area, there is no systematization of the structures and synthesis methods nor their limitations. In this review, all approaches to the synthesis of these compounds, starting from the commercially available pyrene are described. Herein, the ways of obtaining of disubstituted intermediates based on bromination and acylation reaction are presented. This is crucial in the determination of the possibility of further functionalization by using coupling, cycloaddition, condensation, etc. reactions. Moreover, the application of disubstituted pyrenes in the synthesis of 1,3,6,8-tetrasubstituted was also reviewed. This review describes the directions of research on chemistry of disubstituted pyrenes.

“…However, both blue emitters and devices have inherent disadvantages [ [19] , [20] , [21] ]. For blue fluorescent emitters, only singlet excitons can be used to produce light, resulting in the waste of triplet excitons, resulting in internal quantum efficiency (IQE) and external quantum efficiency (EQE) of 25 % and 5 % [ [22] , [23] , [24] ], respectively.…”
