tetraphenylethylene
Sign in to saveTetraphenylethene (TPE) is an organic chemical compound with the formula Ph2C=CPh2, where Ph = phenyl (C6H5). Samples have been described as a yellow solid, but the compound iscolorless. The molecule is crowded such that all four phenyl groups are twisted out of the plane defined by the center six carbon atoms. Tetraphenylethylene is used as a precursor to other organic compounds, often in the area of supramolecular chemistry.
