substituents result in large bathochromic shifts in the chrysene absorption and emission spectra. These newchrysene derivatives show blue fluorescent emission (401–471 nm) with high quantum yields (0.44–0.87). DFT calculations on these chrysenes rationalize well the substituent effects on their HOMO and LUMO energy levels. One representative chrysene (6g) was used as a blue fluorescent emitter in an OLED device
