Rubicene

Rubicene is a polycyclic aromatic hydrocarbon that consists of two benzene and an anthracene. They are each linked by two carbon–carbon bonds. Dilute solutions of rubicene emit strong yellow fluorescence.^[1] It's synthesized from fluorenone by reduction of calcium or magnesium,^[1] or it can be obtained by reacting with dihalogenated diphenylanthracene as raw material.^[2] It can also be obtained by reacting 9,10-diphenylanthracene and 3 parts of DDQ in dichloromethane in the presence of triflic acid.^[2]
