By introducing the methyl substituent acetylacetone and benzyl substituents, Pt(II) complexes restrain Pt–Pt interactions in pure films and maintain nearly identical PL spectra with dilute solution. The maximum EQE of non-doped OLED reaches 19.6%.
ESIPT dyes are synthesized and employed as self-absorption-free luminophores for efficient luminescent solar concentrators (LSCs) with outstanding performance (ηext of 7.19%, PCE of 0.68%, and high AVT of 88%).
We developed two novel stable luminescent radical skeletons, BnBTM and bisBnTM, demonstrating lower frontier orbital energy levels and suppressed nonradiative transition processes than the previously reported radical skeletons.
We present four novel perylene-acene dyads that undergo solvent tuneable emission, based on the presence of a charge transfer state. These dyes were shown to reach photoluminescence quantum efficiencies (PLQEs) as high as 45%.
PLQE enhancement and emission manipulation have been achieved for zero-dimensional (MA)4InCl7 through a metal ion doping strategy. Cs+ or Mn2+ doping result in defect passivation and homogeneous crystals, while Sb3+ doping shift the emission center.
