Perylene diimide isomers containing a simple sp3-core for non-fullerene-based polymer solar cells

In order to investigate the effect of the geometries of perylene diimide (PDI)-based small molecules, five different isomers were synthesized by using a cyclohexane core as a simple sp3-sigma core. Diaminocylohexane is such an effective core for the systematic development of many kinds of isomers via geometric tuning as well as for reducing the self-aggregation tendency of PDIs. Depending on the anchoring position of the PDI units on the cyclohexane core (ortho-, meta- and para-), isomers exhibited differences in solubility and crystallinity. Among the studied isomers, ortho-substituted t-OCP was found to have a highly twisted molecular structure which minimizes the strong tendency towards crystallization due to individual PDI moieties. The unique geometrical nature of the t-OCP isomer led to the highest power conversion efficiency (PCE = 6.23%) of bulk heterojunction (BHJ) polymer solar cells (PSCs) with a higher short-circuit current density (Jsc) and fill factor (FF). It is mainly ascribed to the formation of a nanophase interpenetrating network with well-balanced carrier mobility in the blend film.

Enantioselective Trapping of Oxonium Ylides by 3-Hydroxyisoindolinones via a Formal SN1 Pathway for Construction of Contiguous Quaternary Stereocenters

An enantioselective Rh(II)/chiral phosphoric acid co-catalyzed three-component reaction via trapping of oxonium ylides with 3-hydroxyisoindolinones by a formal SN1 pathway is described. This reaction allows for the efficient synthesis of isoindolinone derivatives with two contiguous quaternary stereogenic centers in high yields (up to 93%) with excellent enantioselectivities and moderate diastereoselectivities under mild reaction conditions.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C20H13O4P, you can also check out more blogs about39648-67-4

Pseudorotaxane based on tetraazamacrocyclic copper complex and dibenzocrown ether

Host-guest interactions between two electron-rich dibenzocrown ethers and electron deficient macrocyclic copper(ii) tetraimine complexes lead to the formation of pseudorotaxane in solution. The interactions are enhanced with the copper(iii) complex compared to that of the copper(ii) form as shown by the electrochemical studies. The larger – 30-membered dibenzocrown donor interacted with the copper complex stronger than the smaller ones as revealed by NMR and electrochemical methods. The thiolated form of the copper(ii) tetraimine complex was self-assembled at the gold electrode forming an electroactive monolayer able to interact with the crown ether in the solution. These donor-acceptor interactions lead to an increase of the barrier properties of the layer and decreased the electron transfer rate between the copper centre and the gold electrode surface as proved by the voltammetric data.

Dimeric yttrium(III) and neodymium(III) macrocyclic complexes: Potential catalysts for hydrolysis of double-stranded DNA

Dimeric complexes of macrocycle L, [{ML(OH)(H2O)}2](NO3)4 where M = Y and Nd, have been prepared via template synthesis. X-Ray structural analysis of [{YL(OH)(H2O)}2]4+ showed each yttrium atom to be coordinated to six nitrogens in the macrocycle, two hydroxide bridging units and one water molecule; the two macrocycles within the dimer have virtually identical conformations. Both dimeric complexes have the remarkable ability to degrade dsDNA, while the corresponding monomers have no activity. Cleavage likely involves random attack at single strands, in which closed circular plasmid DNA is initially converted to a nicked DNA intermediate before final cleavage.
