Triphenylamine-based small-molecule fluorescent probes

Abstract

Three substituted hydrogen with phenyl in the ammonia is known as triphenylamine (TPA), which is one of the most decent compounds by means of its vast practical applications. Chemists have...

Meso‐substituted Metalloporphyrin‐based Composites for Electrocatalytic Oxygen Reduction Reactions

“…The triphenylamine group has the advantages of good electron donating ability, large conjugated system, cheap and easy modification, etc., endowing it with extensive attention to be selected as functional groups for electrocatalysts and sensitizers. [103][104][105][106] In addition, triphenylamine has a propeller-like structure, which is often used to prohibit the aggregation of the molecules to reduce the ineffective intermolecular energy/ electron transfer. [107,108] In recent years, researchers also discovered that triphenylamine can accelerate the collision frequency of the reactive species at the reactive interfaces in both photoinduced and electrocatalytic processes, which is mainly due to the more exposed cationic orbitals on the three phenyl rings.…”

Recent advances in tin ion detection using fluorometric and colorimetric chemosensors

“…Triphenylamine (TPA) is a non-planar, propeller-shaped tertiary amine made up of three aromatic phenyl groups. 104 Although triphenylamine does not display a large amount of fluorescence emission, modified TPA derivatives have been used to make fluorescent probes and electroactive and optoelectronic materials because of their chemical stability, photoluminescence properties, thermal resistance, electroactive properties, and so on. Two triphenylamine-based probes for Sn 2+ detection are described in this section.…”

Design and Synthesis of Benzoheterodiazole‐based Fluorescent Compounds for Emitting Applications

“…[4] On the other hand, triphenylamine (TPA) and triphenylethene (TPE) are common AIEgens appeared in recent studies of aggregation induced emission (AIE) and aggregation induced emission enhancement (AIEE). [5] Among them, triphenylamine (TPA) derivatives have been reported a lot, [6] and the studies about triphenylethene (TPE) derivatives are relatively few. [7] Based on these considerations, we designed and synthesized eight D-A-D compounds (Scheme 1) by Suzuki coupling reactions in order to reveal the possible applications of these cores (BOD, BTD, BSeD and BTZ) as fluorescent materials and to summarize the effect of these AIEgens (TPA and TPE) on their luminescent properties.…”
