Chemistry:1,1,4,4-Tetraphenylbutadiene

From HandWiki

1,1,4,4-tetraphenylbutadiene (TPB) is an organic compound with the formula (C
6H
5)
2C=CHCH=C(C
6H
5)
2. Other isomers are possible, but the term usually refers to the derivative of butadiene with two phenyl group on each of the terminal carbon atoms It is a white solid that has attracted some attention as an electroluminescent dye.[1]

The compound was first prepared by double dehydration of the diol.[2]

It glows blue with an emission spectrum peak wavelength at 430 nm,[3] It is useful as a wavelength shifter.[4][5]
