Functionalized Dibenzo[<i>g</i>,<i>p</i>]chrysenes: Variable Photophysical and Electronic Properties and Liquid−Crystal Chemistry

The photophysical and electronic properties of dibenzo[<i>g</i>,<i>p</i>]chrysenes bearing electron-rich and -deficient substituents vary markedly with these substituents. The chemistry of the first liquid−crystalline dibenzo[<i>g</i>,<i>p</i>]chrysene is also described.
