General Description

11-(bromomethyl)tricosane is a chemical compound belonging to the class of organic compounds known as halohydrocarbons. These are compounds in which a hydrogen atom of a hydrocarbon is substituted by a halogen. Specifically, in 11-(bromomethyl)tricosane, a hydrogen atom is replaced by a bromine atom. This chemical features a bromomethyl group bonded to a tricosane backbone. Tricosane is a long-chain alkane consisting of 23 carbon atoms. The exact properties of 11-(bromomethyl)tricosane such as its physical and chemical properties, uses, toxicity, and environmental effects might not be widely studied and documented in scientific literature.

Conjugated polymers based on dicarboxylic imide-substituted isothianaphthene and their applications in solar cells

Four new polymers containing a benzo[c]thiophene-N-dodecyl-4,5-dicarboxylic imide (DIITN) unit including the homopolymer and three donor-acceptor copolymers were designed, synthesized, and characterized. For these copolymers, DIITN unit with low bandgap was selected as an electron acceptor, whereas 5,5′-(2,7-bisthiophen-2-yl)-9-(2-decyltetradecyl)-9H-carbazole), 5,5′-(3,3′-di-n-octylsilylene-2,2′-bithiophene), and 5,5′-(2,7-bisthiophen-2-yl-9,9-bisoctyl-9H-fluoren-7-yl) were chosen as the electron donor units to tune the highest occupied molecular orbital/lowest unoccupied molecular orbital (HOMO/LUMO) levels of the copolymers for better light harvesting. These polymers exhibit extended absorption in the visible and near-infrared range and are soluble in common organic solvents. The relative low lying HOMO of these polymers promises good air stability and high open-circuit voltage (Voc) for photovoltaic application. Bulk heterojunction solar cells were fabricated by blending the copolymers with [6,6]-phenyl-C61-butyric acid methyl ester or [6,6]-phenyl-C71-butyric acid methyl ester (PC71BM). The best power conversion efficiency of 1.6% was achieved under simulated sunlight AM 1.5G (100 mW/cm2) from solar cells containing 20 wt % of the fluorene copolymer poly[5,5′-(2,7-bisthiophen-2-yl-9,9-bisoctyl-9H- fluoren-7-yl)-alt-2,9-(benzo[c]thiophene-N-dodecyl-4,5-dicarboxylic imide)] and 80 wt % of PC71BM with a high open-circuit voltage (Voc) of 0.84 V.

Exceptionally long-range self-assembly of Hexa-peri-hexabenzocoronene with dove-tailed alkyl substituents

The substitution of a hexa-peri-hexabenzocoronene by bulky, space-demanding, 2-decyltetradecyl side chains proved to be an effective procedure to influence the thermal and self-aggregation behavior. The extremely large steric requirement of the introduced

Comparing the microstructure and photovoltaic performance of 3 perylene imide acceptors with similar energy levels but different packing tendencies

While it is widely recognized that microstructure plays an important role in the performance of organic photovoltaics (OPV), systematic studies are often challenging, as varying the molecular packing through typical chemical means (such as sidechain tuning) often affects the molecular energy levels, thus preventing a clear correlation. In this work we present the synthesis of three perylene imide (PI) based electron acceptors with almost identical energy levels, but distinct packing tendencies. We confirm our initial hypothesis by measuring solution and solid-state absorption, and cyclic voltammetry as well as characterizing the films by grazing incidence wide angle X-ray scattering (GIWAXS). In a second step, we repeat the characterization of the three materials in blends with two polymer donors, namely PCDTBT or PBDBT, whose energy levels are well aligned with those of the PI acceptors, and which, additionally, exhibit different degrees of structural order. We show how the initial strong difference between acceptors is partially blurred in blends, but still critical. Finally, we correlate our structural data with OPV devices made with the corresponding six blends. Our data suggest that a good donor acceptor marriage should ensure good energy alignment but also exhibit complementary crystallization tendencies of the two components. This journal is
