High mobility emissive organic semiconductor

Abstract: The integration of high charge carrier mobility and high luminescence in an organic semiconductor is challenging. However, there is need of such materials for organic light-emitting transistors and organic electrically pumped lasers. Here we show a novel organic semiconductor, 2,6-diphenylanthracene (DPA), which exhibits not only high emission with single crystal absolute florescence quantum yield of 41.2% but also high charge carrier mobility with single crystal mobility of 34 cm2 V−1 s−1. Organic light-emitt… Show more

“…Due to their strong light collecting ability they can mimic the light-harvesting antenna of green sulfur bacteria [81], and their charge mobility is attractive for optoelectronic applications [21]. The crystals can be obtained that combine high carrier mobility with the spectroscopic properties of J-aggregates [82]. However, in solutions with these dyes it is hard to achieve the stability of H-and J-forms.…”

“…The PTTC-based devices had better charge transport characteristics, which was attributed to the improved crystalline ordering and enlarged crystalline domains in pure PTTC films. 34,35 Polymer Solar Cell Properties The photovoltaic properties of the synthesized polymers were determined by preparing bulk heterojunction solar cells with the conventional architecture ITO/PEDOT:PSS/ active layer (polymer:PC 71 BM)/LiF/Al. To compare the impact of only the polymer structure on the photovoltaic properties, identical active layer conditions were used, that is, blend composition (1:3 w/w), concentration (40 mg/mL), and spin-coating conditions (1000 rpm and 60 s), for the two polymer-based solar cell devices [Both PTTC:PC 71 BM and PTVTC:PC 71 BM systems were optimized at the 1:3 w/w blend composition, see Fig.…”

“…Nowadays great achievements have 16 been obtained in organic hole transporting semiconductors. 17 Experimentally, the p-channel organic semiconductors have 18 exhibited remarkable hole mobility approaching 100 cm 2 V À1 s À1 19 [3][4][5][6][7][8][9][10][11][12][13][14][15]. In sharp contrast, development of the n-channel organic 20 semiconductors is much slower.…”
