Usage

Molecular structure

Consists of a fluorene core with two dithiophene groups attached at the 2 and 7 positions.

Chemical composition

Made up of carbon, hydrogen, and sulfur atoms.

Physical properties

Soluble in common organic solvents due to the presence of dioctyl substituents on the fluorene core.

Electronic properties

High charge carrier mobility, which makes it useful in conductive polymers and organic electronic materials.

Film-forming properties

Can be processed easily in thin-film electronic device fabrication.

Applications

Organic photovoltaics, organic field-effect transistors, and organic light-emitting diodes.

Fullerene-free small molecule organic solar cells with a high open circuit voltage of 1.15 V

A new small molecule named DTBTF with thiobarbituric acid as a terminal group was designed and synthesized as an acceptor for organic photovoltaic applications. DTBTF exhibits strong absorption in the visible region, and a relatively high lying LUMO energy level (-3.62 eV). All-small-molecule organic solar cells based on DR3TSBDT:DTBTF blend films show a considerable PCE of 3.84% with a high Voc of 1.15 V.

Polyarylene synthesis by cross-coupling with HOMSi reagents

Cross-coupling reaction of dibromoarenes with HOMSi reagents (organo[2-(hydroxymethyl)phenyl]dimethylsilanes), or alternatively bromoarenes with arylene-bisHOMSi reagents, proceeded smoothly in the presence of a Pd catalyst and a weak base, and ter- or quaterarenes are produced in excellent yields. The present reaction was successfully applied to polyarylene synthesis using 4,7-dibromobenzothiadiazole or a 2,7-dibromofluorene derivative along with a 2,7-fluorenylenebisHOMSi reagent.
