Application

  • Design of hole transport materials: New small derivatives of 2,2′-bithiophene, possibly involving Diphenylamine as a building block, were rationally designed to improve the performance of perovskite solar cells, demonstrating Diphenylamine′s role in advancing photovoltaic technology (Adadi et al., 2024).
  • High-efficiency hyperfluorescent OLEDs: Diphenylamine may be implicated in the development of hybridized local and charge transfer dendrimers, aimed at achieving near-unity exciton utilization in solution-processed OLEDs, highlighting its potential in high-performance electronic displays (Yin et al., 2024).
  • Chemical detection technologies: A benzoxazole-triphenylamine conjugated fluorogenic probe was developed for the specific detection of sarin gas mimic diethylchlorophosphate, illustrating Diphenylamine′s utility in sensitive and specific chemical sensors (Sultana et al., 2024).
  • Electrochemiluminescence emitters: Diphenylamine-based emitters were tailored for efficient electrochemiluminescence, employing tripropylamine as a co-reactant, contributing to the field of electrochemical sensors and displays (Morgan et al., 2023).
  • Near-infrared fluorophores development: Research on chlorinated rylenecarboximide fluorophores, potentially involving Diphenylamine, focused on efficient near-infrared applications, which are critical for advanced imaging and diagnostic techniques (Wu et al., 2023).
