Abstract

Abstract: 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 1.3cd/A (1.00lm/W at 5.17V) and D2 had the maximum light-to-electricity efficiency of 4.57% under AM 1.5 solar simulator (100mWcm−2). The results suggest that bistriphenylamine-substituted fluoranthene derivatives have the potential application in optoelectronic materials. [Copyright &y& Elsevier]

Abstract

Abstract: Six new organic dyes, TBS1–TBS6, have been synthesized and characterized by optical, electrochemical, and theoretical studies. Among these dyes, DSSCs based on a dye containing N-hexylcarbazole and furan moieties (TBS4) showed the best performance, with light-to-electricity conversion efficiency up to 5.91% under AM 1.5 solar simulator, much higher than the reference dye TPS (4.24%). The high V oc contributed to the good performance for TBS4, which may be ascribed to the combined effects of twisted structure and hexyl chain. Additionally, for TBS4 based DSSCs, under optimized conditions, the light-to-electricity conversion efficiency was enhanced up to 7.09%. The results suggest that dibenzo heterocycles containing dyes are promising candidates for application in DSSCs. [Copyright &y& Elsevier]
