Conjugation Pathway of Benzobisoxazoles in Polymer Donors Mediates the Charge Management and Enables Organic Solar Cells with Record Certified Efficiency

open access: yesAdvanced Materials, EarlyView.
Herein, the conjugation pathway isomerism of the benzobisoxazole (BBO) building block is systematically compared, by which a certified efficiency of 19.1% is obtained in corresponding all‐polymer solar cells. Abstract Charge management plays a pivotal role in achieving high‐performance bulk heterojunction (BHJ) organic solar cells (OSCs). In this study,

One‐Pot Single‐Step Approach for the Controlled Synthesis of Multifunctional Microparticles

open access: yesAdvanced Materials, EarlyView.
A versatile one‐pot strategy combines bipolar electrochemistry and the water‐organic interface to synthesize in a single‐step complex patchy particles, which cannot be achieved by any other deposition process. Under the influence of an electric field, microparticles undergo selective surface modification via coupled redox reactions, enabling ...

Charge Transfer-oxy Radical Mechanism for Anti-cancer Agents [PDF]

open access: yes, 1986
The proposal is advanced that anti-cancer drugs generally function by charge transfer resulting in formation of toxic oxy radicals which destroy the neoplasm.

Single‐Crystal Organic Field‐Effect Transistors Based on 5,15‐Bisaryl‐Tetrabenzoporphyrins: Synthesis, Structure, and Charge Transport Properties

open access: yesAdvanced Materials Interfaces, EarlyView.
This study explores single‐crystal organic field‐effect transistors (SC‐OFETs) based on 5,15‐bisaryl‐tetrabenzoporphyrin derivatives. It highlights the impact of meso‐substituted groups on molecular packing and charge transport. Among the derivatives, C8Ph‐BP achieves the highest hole mobility (1.64 cm2 V−¹ s−¹) due to enhanced π‐stacking with ...

Quinone-based Switches for Candidate Building Blocks of Molecular Junctions with QTAIM and the Stress Tensor [PDF]

open access: yesarXiv, 2018
The current work investigates candidate building blocks based on molecular junctions from hydrogen transfer tautomerization in the benzoquinone-like core of an azophenine molecule with QTAIM and the recently-introduced stress tensor trajectory analysis.

Nano‐Octahedron Cobalt Oxide Decorated Graphene Nanocomposites for the Selective/Simultaneous Detection of Dopamine

open access: yesAdvanced Materials Interfaces, EarlyView.
Nano‐octahedron Co3O4 decorated graphene composite electrode for selective and simultaneous detection of dopamine. The detection limit of 0.09 µM, and linear range from 1 to 500 µM are reported. The synergistic effect of nano octahedron Co3O4 and graphene results in excellent performance of the sensor in terms of selectivity and sensitivity.

The persistence of self-employment across borders: new evidence on legal immigrants to the United States [PDF]

open access: yes, 2007
Using recently-available data from the New Immigrant Survey, we find that previous self-employment experience in an immigrant’s country of origin is an important determinant of their self-employment status in the U.S., increasing the probability of ...
