Corannulene's outer rim was regio-selectively functionalized with ethynyl units at both 1,8 and 1,5-positions and later coupled with phenyl and anthracenyl moieties to study the extent of conjugation through the aromatic framework of corannulene via absorption/emission spectra. Experimental observations were compared with TD-DFT calculations at the level of CAMB3LYP/6-31G* and B3LYP/6-31G*. Laser excitation experiments reveal blue emission for 1,8-bis(phenylethynyl)corannulene and 1,5-bis(phenylethynyl)corannulene which quickly transforms into intense blueish-green in the case of 1,8-bis(9-anthranyl)corannulene and 1,5-bis(9-anthranyl)corannulene.
