TPE-TOH: A Luminescent Pioneer in Organic Optoelectronic Materials
The field of organic optoelectronic materials is continuously advancing, with compounds like TPE-TOH emerging as significant contributors. With its distinctive aggregation-induced emission (AIE) effect and its role as a synthetic intermediate for more complex derivatives, TPE-TOH is solidifying its position in the domain.
Understanding TPE-TOH
4,4′,4′′,4′′′-(Ethene-1,1,2,2-tetrayl)tetraphenol, commonly known as TPE-TOH, is a derivative of tetraphenylethylene (TPE) enriched with four hydroxyl groups. In a THF solution, this molecule remains predominantly non-emissive. However, the addition of water initiates an intense blue fluorescence, attributed to the aggregation-induced emission (AIE) effect.
Key Features of TPE-TOH
