Recent advances in boron-based schiff base derivatives for organic light-emitting diodes

Organic light-emitting diodes (OLEDs) are well known in display, signage, and lighting potential applications. However, the development of organic semiconductors started 100 years back by Pochettino in 1906 with the discovery of the photoelectric effect in anthracene crystals. Over the recent past, a lot of efforts have been spent to increase device efficiency and lifetime, which permits organic electroluminescence in the display and lighting market. Degradation of materials is the major obstacle for the development of highly efficient and economically feasible and durable organic light-emitting devices for commercial applications. In this progressive review article, we have consolidated the recent advances in the elucidation of materials degradation due to possible crystal defects and pi-conjugated structures having high carrier mobility in organoboron compounds, which make them to be appropriate in optoelectronics including OLEDs. Various chelating ligands and boron moieties have been researched and explored to construct stable electronic structural molecules in four-coordinated boron compounds, which play significant roles on the photophysical and electronic properties. In this review article, we provided the overview of the materials degradation, construction, and durability of organoboron compounds with enough prominence photophysical data. (c) 2018 Elsevier Ltd.
