Ternary blending as one of the most successful strategies has achieved continuous performance breakthroughs in organic solar cells(OSCs)over the past few years.Here,a small molecule featuring a dithieno[3,2-f:2′,3′-...Ternary blending as one of the most successful strategies has achieved continuous performance breakthroughs in organic solar cells(OSCs)over the past few years.Here,a small molecule featuring a dithieno[3,2-f:2′,3′-h]phthalimide derivative as the intermediate unit,named DTP-C8-R,is designed and utilized as the third component to construct ternary OSCs(TOSCs).The increased molecular packing of L8-BO as well as the charge transfer excitons between PM6 and DTP-C8-R lead to a very low nonradiative energy loss of 0.179 eV and a high open-circuit voltage(V_(OC))of 0.910 V in the TOSCs based on the PM6:L8-BO host blend.Moreover,the DTP-C8-R:PM6:L8-BO film(0.05:0.95:1.2,w/w)possesses better fibrous nanophase separation and the enhancedπ-πstacking ordering of the acceptors with a larger crystal coherence length compared with the PM6:L8-BO blend film,so the TOSCs present more efficient exciton dissociation,longer carrier lifetime,faster carrier transport and less charge recombination.It boosts the power conversion efficiency to 19.22%with a short-circuit current density of 27.10 mA cm^(-2).This work demonstrates that the small molecule based on a dithieno[3,2-f:2′,3′-h]phthalimide derivative as the minor component is an executable strategy to achieve high-performance TOSCs with high V_(OC).展开更多

Thirty-one patients received CHOPR-like treatment （rituximab 375 mg/m2 1 day before CHOP-like chemotherapy）. Twenty patients received CHOP-like regimen in combination with peginterferon （pegIFN） （1μg/kg on day 5） and rituximab （on day 6）.RESULTS -The CR （complete remission） rate in the CHOPR-like （with or without pegIFN） group and in the CHOP-like group was 78.4% and 45.1% （P = 0.005）, respectively. The estimated mean time of overall survival （OS） in the CHOPR-like group and CHOP- like group was 58.7 ± 2.8 and 36.4 ±3.4 months, respectively （P = 0.002）. The rates of CR and OR （overall remission） in CHOPR- like with IFN arm were 85.0% and 95.0%, and the rates of those in CHOPR-like without IFN arm were 74.2% and 87.0% （P 〉 0.05）. The estimated mean time of 4-year-PFS （progression- free survival） in CHOPR-like with IFN arm and in CHOPR-like without IFN arm was 62.9 ±3.0 months and 51.0 ± 4.6 months （P = 0.092）, respectively. In the CHOPR-like with IFN arm, no patient relapsed after achieving CR, while the estimated rate of 4-year- DFS （disease-free survival） in the patients who reached CR in the CHOPR-like without IFN arm was （63.4 ± 19.3）% （P = 0.061）. CONCLUSION Rituximab combined with CHOP-like chemotherapy improved the prognosis of DLBCL patients. The IFN may help to improve the quality and duration of response of DLBCL patients treated with rituximab and CHOP-like regimen.展开更多
