“…A series of tritopic ligands based on a benzene scaffold have been prepared (Table 7), with the compound 1,3,5-tris(di-2-pyridylamino)benzene 59 having attracted significant attention since it was first reported by Wang et al [122] Like other related compounds, 59 was prepared from 1,3,5-tribromobenzene and di-2-pyridylamine via copper-mediated Ullmann condensations in good yield.…”

The photoluminescence and electron drift mobility of newly synthesized 1,3,5-triazine derivatives were investigated. 1,3,5-Triazine derivatives with one or two 4-(arylethynyl)phenyl groups had single photoluminescence peaks in the blue region, 405-452 nm, in the deposited films. Time-of-flight measurement revealed that electron transport in the films of certain 1,3,5-triazine derivatives was non-dispersive and electron drift mobilities were in the range of 10 -5 -10 -4 cm 2 V -1 s -1 . OLED devices incorporating 1,3,5-triazine derivatives in the emitting layer had pure blue luminescence at 437 nm and 444 nm. Moreover, these compounds were also able to be used as an electron-transport layer.

“…Besides, nonplanar molecules such as triarylamines, spiro-compounds, and 1,3,5-triphenylbenzene or 2,4,6-triphenyltriazine exhibit mobilities in the range of 10 -2 to 10 -5 cm 2 /Vs [84]. Compounds such as quinoxaline, benzimidazole, pyridine, and oxadiazole having electron-withdrawing properties [85,86] are found to be useful for device applications, for instance, materials such as 1,3,5-tris(9,9-dimethylfluoren-2-yl) benzene [87] and 2,4,6-tris[di(2-pyridyl)amino]-1,3,5-triazine offer better form of electron transport layers (ETLs) for OLED applications [88].…”

Abstract:With the rich experience of developing silicon devices over a period of the last six decades, it is easy to assess the suitability of a new material for device applications by examining charge carrier injection, transport, and extraction across a practically realizable architecture; surface passivation; and packaging and reliability issues besides the feasibility of preparing mechanically robust wafer/substrate of single-crystal or polycrystalline/ amorphous thin films. For material preparation, parameters such as purification of constituent materials, crystal growth, and thin-film deposition with minimum defects/ disorders are equally important. Further, it is relevant to know whether conventional semiconductor processes, already known, would be useable directly or would require completely new technologies. Having found a likely candidate after such a screening, it would be necessary to identify a specific area of application against an existing list of materials available with special reference to cost reduction considerations in large-scale production. Various families of organic semiconductors are reviewed here, especially with the objective of using them in niche areas of large-area electronic displays, flexible organic electronics, and organic photovoltaic solar cells. While doing so, it appears feasible to improve mobility and stability by adjusting π-conjugation and modifying the energy bandgap. Higher conductivity nanocomposites, formed by blending with chemically conjugated C-allotropes and metal nanoparticles, open exciting methods of designing flexible contact/interconnects for organic and flexible electronics as can be seen from the discussion included here.
