Bright perovskite light-emitting diodes with improved film morphology and reduced trap density via surface passivation using quaternary ammonium salts

Organic electronics, 2019
Organic-inorganic hybrid perovskite light-emitting diodes (PeLEDs) have emerged as one of the promising candidates for display and illumination devices with low-cost and high color purity.

Synthesis of quaternary ammonium salts

1997
Since the early days of phase transfer catalysis (PTC), the most popular catalysts have been quaternary ammonium salts (quats). Among these, tetra- H-butylammonium bromide (TBAB), introduced by Brandstrom, triethyl- benzylammonium chloride (TEBA), initiated by Maskoza, and Stark’s tricaprylmethylammonium chloride (Aliquat 336 or Adogen 464) are more ...

Quaternary ammonium salts as colloidal electrolytes

Journal of Colloid Science, 1946
Abstract 1. 1. Freezing point depressions in solutions of dodecylbenzyldimethylammonium chloride and sulfamate have been measured. The osmotic coefficients of the chloride fall midway between the generalized curves of McBain and Brady for straight and branched chain compounds. The sulfamate is less associated in dilute solutions than the chloride.
