Unveiling the important role of non-fullerene acceptors crystallinity on optimizing nanomorphology and charge transfer in ternary organic solar cells

The crystallinity of non-fullerene acceptors as the third component has an important role on nanomorphology optimization and charge transfer dynamics of ternary organic solar cells (OSCs). Herein, efficient ternary OSCs were fabricated by incorporating two typical non-fullerene acceptors with different crystallinity, (Z)-5-{[5-(15-{5-[(Z)-(3-Ethyl-4-oxo-2-thioxo-1,3-thiazolidin-5-ylidene)methyl]-8-thia-7.9-diazabicyclo [4.3.0] nona-1 (9),2,4,6-tetraen-2-yl}-9,9,18,18-tetrakis (2-ethylhexyl)-5.14-dithiapentacyclo [10.6.0.0(3,10).0(4,8).01(3,17)]octadeca-1(12),2,4(8),6,10,13 (17),15-heptaen-6-yl)-8-thia-7.9-diazabicyclo [4.3.0]nona-1 (9),2,4,6-tetraen-2-yl]methylidene}-3-ethyl-2-thioxo-1,3-thiazolidin-4-one (EH-IDTBR) or (5Z, 5’Z)-5,5′-((7,7′-(4,4,9,9-tetraoctyl-4,9-dihydro-s-indaceno [1,2-b:5,6-b’]dithiophene-2,7-diyl)bis (benzo [c][1,2,5]thiadiazole7,4diyl)) bis(methanylylidene))bis (3-ethyl-2-thioxothiazolidin-4-one) (O-IDTBR), into the host donor/acceptor active layers comprising of poly (3-hexythiophene-2,5-diyl) (P3HT) and [6,6]-phenyl-C71-butyric acid methylester (PC71BM). As a result, the 21.5% and 22.7% increase of the power conversion efficiency (PCE) for the two ternary systems were achieved, respectively, which was attributed to the enhanced light harvesting capability, optimized bulk-heterojunction morphology and the formation of cascade energy level alignments that could introduce an additional pathway for efficient charge transfer. Although both the short-circuit current density (Jsc) and fill factor (FF) values were increased significantly by regulating the weight ratios of non-fullerene acceptors of two ternary systems, the O-IDTBR-based ternary OSCs showed the higher Jsc while P3HT:EH-IDTBR:PC71BM system exhibited the higher FF values. The main difference of improved photovoltaic performance in the two ternary systems could be associated with the different blend morphology and charge carrier mobilities. In addition, nanomorphology studies suggested that lamellar stacking coherence lengths of P3HT in face-on orientation for EH-IDTBR- and O-IDTBR-based systems can be increased from 18.48 nm to 20.94 nm and 21.67 nm respectively, resulting from the stronger crystallinity of O-IDTBR than that of EH-IDTBR, which was beneficial for charge transport in the vertical direction. These results indicate that selecting the appropriate crystalline non-fullerene acceptors may be an effective strategy to optimize nanomorphology to further achieve high efficiency ternary OSCs.

THE ANALGESIC EFFECT OF 1,3-THIAZOLIDIN-4-ONE DERIVATIVES AS POTENTIAL MODULATORS OF THE SEROTONINERGIC SYSTEM

This study presents the synthesis and evaluation of the analgesic effect of 1,3-thiazolidin-4-one derivatives. Tested compounds were prepared by the cyclization reaction of appropriate N-substituted carboxylic acid hydrazide derivatives with mercaptoacetic acid. The purpose of this study was the evaluation of the analgesic properties of 1,3-thiazolidin-4-one derivatives. In addition to this, we tried to explain the role of serotonin receptors in the antinociceptive mechanisms of tested compounds. The experiments were carried out using male Albino Swiss mice (20-25g). The compounds were administered intraperitoneally (ip) and were analysed for analgesic activities in models of pain in mice. Additionally, they were tested for safety on the central nervous system of mice in selected behavioural tests. Our results revealed an interesting analgesic activity of the tested compounds. The tested derivatives showed low toxicity, reflected by their LD50 value. Moreover, none of these compounds exhibited neurotoxic properties or impaired the cognitive activity of mice, even at the highest doses used. All tested derivatives showed analgesic activity. Among the tested compounds, N-[2-(4-methylphenyl)-4-oxo-1,3-thiazolidin-3-yl] acetamide seems to be the most effective painkiller. It has a pronounced antinociceptive effect towards thermal and mechanical pain stimulation. The present results support the idea that 5-HT receptors play an important role in the control of pain. The compounds that modulate 5-HT receptors activity may have clinical utility in pain therapy.
