Bistriphenylamine-substituted fluoranthene derivatives as electroluminescent emitters and dye-sensitized solar cells

A novel series of compounds containing fluoranthene and triphenylamine were designed and synthesized as electroluminescent materials or sensitizers. Photophysical and electrochemical measurements were carried out on these compounds. DPBF exhibited a maximum current efficiency of 1.3 cd/A (1.00 lm/W at 5.17 V) and D2 had the maximum light-to-electricity efficiency of 4.57% under AM 1.5 solar simulator (100 mW cm−2). The results suggest that bistriphenylamine-substituted fluoranthene derivatives have the potential application in optoelectronic materials.
