Organic compounds prepared from 1- position activated 9-phenylcarbazole interconnected with diphenyltriazine functionalized carbazole were examined as bipolar host materials of phosphorescent and thermally activated delayed fluorescent organic light-emitting diodes. Interconnection position of the 9-phenylcarbazole was 1- position, and that of diphenyltriazine functionalized carbazole was changed from 1- position to 4- position. Main influence of the interconnection position was current density of the device and 2- or 3- position interconnection increased current density of the devices. All host materials derived from the 1- position activated 9-phenylcarbazole performed well as the host of phosphorescent and thermally activated delayed fluorescent organic light-emitting diodes.

Reported is a new fluorescent probe based on boron?dipyrromethene dye (BODIPY) for late endosome staining in live cells. Among the 14 pH-responsive BODIPY-based far-red/near-infrared dyes used, it was found that a (4-methyl-1-piperazinyl)phenyl-substituted BODIPY could stain late endosomes in three different cell lines. This BODIPY dye was applicable for measurement of the fusion time of late endosomes and lysosomes, thereby demonstrating the utility of this dye for functional analyses of late endosomes in live cells.

A highly soluble fluorene-triphenylamine conjugated alternating copolymer (PF-TPA) was designed and synthesized under Suzuki coupling reaction conditions in this work. The structure of the copolymer was characterized by Fourier transform infrared (FT-IR) spectroscopy, and hydrogen and carbon nuclear magnetic resonance (1H-NMR, 13C-NMR). The copolymer showed excellent thermal stability, and an onset decomposition temperature up to 443 C. The optical and electrochemical properties of PF-TPA were investigated by using ultraviolet visible (UV-vis) absorption spectroscopy, photoluminescence (PL) spectroscopy, transient photocurrent responses and cyclic voltammetry (CV). The main absorption peak of PF-TPA appeared at lambdamax = 382 nm in the thin film and exhibits strong photoluminescence with maximum emission peaks centered at 464 nm in chloroform. The simulation results of the highest occupied molecular orbital (HOMO), lowest unoccupied molecular orbital (LUMO) and energy band gap are ?5.04, ?2.22 and 2.82 eV, respectively. A non-volatile rewritable flash memory device based on the active layer of PF-TPA was fabricated with the sandwich structure ITO/PF-TPA (102 nm)/Al. The memory device exhibits good electrical bistable resistive switching behavior, with low threshold voltage (VSET ? ?1.2 V and VRESET ? 3.2 V), high ON/OFF current ratio in excess of 103, high stability in retention time up to 104 s and a number of read cycles up to 300 under a read voltage of 2 V in both ON and OFF states. The conductivity mechanism of the ITO/PF-TPA/Al device is discussed. The as-fabricated device exhibited good data retention characteristics, stability and reliability.

To establish a structure?property relationship between polymer backbone structures and field-effect transistor performance has emerged as a new topic in organic electronics. The tunability and diversity of organic semiconductors provide the feasibility of controlling the electrical properties. Herein the characterization of thienothiophene-, dithiophenylethene-, biselenophene-, and diselenophenylethene-containing azaisoindigo copolymers is presented. As suggested by both theoretical calculations and experimental results, backbone electronic structure and linearity, density of side chains, aggregation, and thin film microstructure are involved in the differences in optical and electrical properties of these polymers. As the conjugation lengthens, n-type behaviors of the polymer semiconductors are suppressed, leading to a variation from nearly balanced ambipolar behaviors to predominant p-type characteristics. The effect of heteroatom substitution is also investigated. Notably, high hole and electron mobilities of 1.14 and 1.54 cm2 V?1 s?1 extracted from approximately ideal I?V curves are achieved with the top-gate/bottom-contact configuration transistors, demonstrating the potential of 7,7?-diazaisoindigo-based semiconducting polymers for applications in organic electronics.

Background: Since its discovery on the 1930 decade, phthalocyanines have occupied a prominent place in the textile and dye industries due to their thermal stability, low solubility and reactivity. However, over the last three decades, many different applications have been found for phthalocyanine derivatives including medicine, materials science, catalysis and energy fields. In this review, we discuss about the phthalocyanine chemistry, and the principal synthetic precursors as well. Strategies developed for obtaining soluble and non-aggregated phthalocyanine dyes are also covered, with insights on the reaction mechanisms. The main synthetic methods for the synthesis of symmetric and non-symmetric systems are presented and discussed. Objective: This review aims to present an overview on phthalocyanine chemistry and their principal synthetic precursors, covering strategies developed for obtaining soluble and non-aggregated phthalocyanine dyes with insights on the reaction mechanisms. Also, the main synthetic methods are presented, and different approaches to symmetric and non-symmetric phthalocyanine are discussed. Conclusion: Phthalocyanines are compounds with significant applications and growing interest in science. Their physical and chemical properties have been more and more elucidated. The major challenge is to make the synthetic protocols more suitable and cheaper, in order to allow studies and application on large scales.

Direct and selective mono-N-pyridylation of trans-(R,R)-cyclohexane-1,2- diamine is described here. Facile preparation of a novel chiral 2-aminoDMAP core catalaphore via Cu catalysis has led to the development of various sulfonamide/2-aminoDMAPs as bifunctional acid/base organocatalysts (most in two steps overall), which have been shown to very effectively promote asymmetric conjugate addition of acetylacetone to trans-beta-nitroolefins with good to excellent yields (87-93%) and enantioselectivites (up to 99%).

Pd-Catalyzed Autotandem Reactions with N-Tosylhydrazones. Synthesis of Condensed Carbo- and Heterocycles by Formation of a C-C Single Bond and a C-C Double Bond on the Same Carbon Atom

A new Pd-catalyzed autotandem reaction is introduced that consists of the cross-coupling of a benzyl bromide with a N-tosylhydrazone followed by an intramolecular Heck reaction with an aryl bromide. During the process, a single and a double C-C bond are formed on the same carbon atom. Two different arrangements for the reactive functional groups are possible, rendering great flexibility to the transformation. The same strategy led to 9-methylene-9H-fluorenes, 9-methylene-9H-xanthenes, 9-methylene-9,10-dihydroacridines, and also dihydropyrroloisoquinoline and dihydroindoloisoquinoline derivatives.
