Tetraphenyl butadiene (1,1,4,4-tetraphenyl-1,3-butadiene or TPB) is an organic compound with the formula [(C6H5)2C=CH]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. [3]
The compound was first prepared by double dehydration of the diol. [4]
It glows blue with an emission spectrum peak wavelength at 430 nm, [5] It is useful as a wavelength shifter. [6] [7]
