Oznake: conjugated microporous polymers;isoindigo;semiconductors;conductivity;electron mobility;
The development of n-type organic semiconductors has evolved significantly slower in comparison to that of p-type organic semiconductors mainly due to the lack of electron-deficient building blocks with stability and processability. However, to realize a variety of organic optoelectronic devices, hi ...

Oznake: isoindigo;CO2 reduction;formate;photocatalysis;covalent organic frameworks;
Photocatalytic CO2 reduction into formate (HCOO–) has been widely studied with semiconductor and molecule-based systems, but it is rarely investigated with covalent organic frameworks (COFs). Herein, we report a novel donor–acceptor COF named Co-PI-COF composed of isoindigo and metallated porphyrin ...

Oznake: 3D-structures;density functional theory;hydrogen peroxide;isostructural materials;metal-organic framework;photocatalysis;
Photocatalytic hydrogen peroxide (H2O2) generation via sunlight-driven water and oxygen reduction reactions presents a sustainable alternative to the energy-intensive anthraquinone process. Although metal–organic frameworks (MOFs) offer tunable platforms for photocatalysis, the influence of metal–li ...
