“…The construction of the C-S bond is one the most significant transformations in modern organic synthesis, as molecules containing the C-S bond are mostly found in abundance in biomolecules, pharmaceutical drugs, 104 dyes 105 and many more significant materials. Drugs like vortioxetine 106,107 (antidepressant), sertaconazole 108 (anti-fungal) and organic semiconductors like BTBT, DNT 109 are also important sulphur-containing compounds.…”

“…Fused thiophene units are one of the most popular building blocks utilized in organic π-conjugated materials [ 84 , 85 , 86 ]. The first potential application in OLEDs was achieved using dithienothiophene (DTT) as an electron donor with triarylborane terminal groups ( 61 ) in 2005 by Mazzeo et al ( Figure 10 ) [ 87 ].…”

Multidisciplinary research on organic fluorescent molecules has been attracting great interest owing to their potential applications in biomedical and material sciences. In recent years, electron deficient systems have been increasingly incorporated into fluorescent materials. Triarylboranes with the empty p orbital of their boron centres are electron deficient and can be used as strong electron acceptors in conjugated organic fluorescent materials. Moreover, their applications in optoelectronic devices, energy harvesting materials and anion sensing, due to their natural Lewis acidity and remarkable solid-state fluorescence properties, have also been investigated. Furthermore, fluorescent triarylborane-based materials have been commonly utilized as emitters and electron transporters in organic light emitting diode (OLED) applications. In this review, triarylborane-based small molecules and polymers will be surveyed, covering their structure-property relationships, intramolecular charge transfer properties and solid-state fluorescence quantum yields as functional emissive materials in OLEDs. Also, the importance of the boron atom in triarylborane compounds is emphasized to address the key issues of both fluorescent emitters and their host materials for the construction of high-performance OLEDs.

“…In recent years, fused thiophene systems for instance thienothiophene (two annulated units of thiohpene), DTT (three fused subunits of thiophene), and thienoacenes (more than three annulated units of thiophene) are being found more compatible in tuning the band gap, and display diverse potential applications ranging from the OLEDs, OFETs, solar cells, organic dyes, uorescent probes, to the chalcogen bonded cascades etc. [18][19][20][21][22][23][24][25][26][27][28] Among the fused thiophene systems, dithieno[3,2-b:2 ′ ,3 ′ -d]thiophene 2 and its congeners have fully-edged due to their inimitable architecture, which can be treated as sulfur atom bridging 2,2 ′ -bithiophenes 1, consisting one of the sulfur atom (central one) pointing in the opposite direction to that of the other two peripheral ones (Fig. 1).…”
