Aggregation induced emission small molecules for blue light-emitting electrochemical cells

An efficient heterodinuclear Ir(iii)/Pt(ii) complex: synthesis, photophysics and application in light-emitting electrochemical cells

“…For instance, Zhou and co-workers report on the successful application of Ir and Pt homodinuclear complexes as the emitter in OLEDs that exhibit a very high efficiency, 13,22 while others have demonstrated well-performing OLED devices based on homodinuclear and heterodinuclear complexes that emit with a broad variety of emission colors at high efficiency. 2 The light-emitting electrochemical cell (LEC) features a number of distinct advantages over the OLED, notably the opportunity to employ a robust single-layer active material and air-stabile electrodes, [23][24][25][26][27][28][29] which in turn render the LEC an ideal candidate for a low-cost 30 and low-energy solution-based [31][32][33][34][35][36] fabrication. However, only a few examples on the employment of multinuclear complexes in LEC devices exist in the scientific literature.…”

Facile generation of thenil and furil based blue emitters for the fabrication of non-doped and solution-processed light-emitting electrochemical cells

“…The HOMO energy values estimated using these onset values, using the equation E HOMO = −( E onset ox + 4.4) eV, were found to be −5.09 and −4.96 eV for ThAm and FuAm , respectively. 26 Correspondingly, the LUMO energy values were calculated from the reduction onset values and were found to be −2.64 and −2.62 eV for ThAm and FuAm , respectively.…”

“…Various building blocks were introduced into the LEC library until now, including phenanthroimidazole and phenothiazine coupled with aromatic groups like pyrene, tetraphenylene ethylene, anthracene, carbazole, and triazine, to harvest excellent performing devices. 26–30 The main backbone structure used in the majority of the organic SM based studies is based on phenanthroimidazole or phenothiazine. 28,31–33…”

Recent Progress on Light‐Emitting Electrochemical Cells with Nonpolymeric Materials

“…This could offer further simplicity and applicability of a variety of materials. In this section, we highlight current advances in ionic-material LECs, namely, iTMCs, [31, iSMs, [97][98][99][100][101][102][103][104][105][106][107][108][109] and perovskite LECs, [113][114][115][116][117][118] in terms of luminance efficiency, device lifetime, and recent approaches for future applications.…”

“…Consequently, ionic SM LECs have been well investigated. [97][98][99][100][101][102][103][104][105][106][107][108][109] In 2015, Choe and co-workers synthesized an ionic fluorine derivative (Figure 7a). [97] The acetonitrile solution of this material showed a PL peak at 420 nm and a PLQY of 77 %.…”
