Photoluminescence: Applications

1.2K
Photoluminescence offers a wide range of applications due to its inherent sensitivity and selectivity. This technique allows for both direct and indirect analyses of the analyte. Direct quantitative analysis is possible when the analyte exhibits a favorable quantum yield for fluorescence or phosphorescence. However, an indirect analysis may be feasible if the analyte is not fluorescent or phosphorescent, or if the quantum yield is unfavorable. Indirect methods include reacting the analyte with...

Area of Science:

  • Materials Science
  • Organic Electronics
  • Photophysics

Background:

  • Folded thermally activated delayed fluorescence (TADF) molecules based on through-space charge transfer (TSCT) are of increasing interest.
  • However, their electroluminescence (EL) efficiencies are often inferior, and their use as sensitizers for multi-resonance TADF (MR-TADF) emitters is underexplored.

Purpose of the Study:

  • To design and synthesize novel isomeric folded TADF molecules (f-TRZ-1 and f-TRZ-2).
  • To investigate their potential as emitters and sensitizers in organic light-emitting diodes (OLEDs).

Main Methods:

  • Synthesis of f-TRZ-1 and f-TRZ-2 using 2,4,6-triphenyl-1,3,5-triazine (TRZ) as acceptor, 9-phenylcarbazole (PC) as donor, and 11,12-dihydroindolo[2,3-a]carbazole (HIC) as bridge.
  • Fabrication and characterization of OLEDs using these molecules as emitters.
  • Evaluation of their performance as sensitizers for a green MR-TADF emitter.

Main Results:

  • The synthesized molecules exhibit effective TSCT, ultrahigh thermal stability, and balanced bipolar charge transport.
  • OLEDs utilizing f-TRZ-1 and f-TRZ-2 as emitters achieved maximum external quantum efficiencies (ηext,max) up to 28.9%.
  • As sensitizers for a MR-TADF emitter, they improved ηext,max to 37.8% and reduced efficiency roll-off in hyperfluorescence OLEDs.

Conclusions:

  • The novel folded TADF molecules demonstrate excellent potential as high-performance emitters in OLEDs.
  • Their application as sensitizers for MR-TADF emitters significantly enhances device performance, showcasing their versatility.
