Hydrogen-bonded oligothiophene rosettes with a benzodithiophene terminal unit: self-assembly and application to bulk heterojunction solar cells

Self-assembly and conductivity of hydrogen-bonded oligothiophene nanofiber networks.

Symmetric oligothiophene derivatives containing hydrogen bond forming segments create self-supporting organogels consisting of self-assembled 1D nanostructures at low concentrations. Hydrogen bond formation and π-π stacking were both found to be crucial for the formation of conductive supramolecular networks of 1D nanostructures.

Hydrogen bonding in bulk heterojunction solar cells: A case study

Small molecules with dithieno[3,2-b;2',3'-d]thiophene as central building block and octyl cyanoacetate and octyl cyanoacetamide as different terminal building blocks have been designed and synthesized. The amide containing small molecule can form intermolecular hydrogen bonding between N-H...O = C of the amide group. The photovoltaic properties and active layer morphologies of the two molecules...

Bulk Heterojunction Solar Cells — Opportunities and Challenges

Hydrogen-bond self-assembly of DNA-analogues into hexameric rosettes.

The self-assembly of a DNA-analogue hexameric rosette from triaminopyrimidine and cyanuric acid-based nucleosides, and its subsequent aggregation into rod-like morphologies is reported.
