Thermodynamic Property-Performance Relationships in Silicon Phthalocyanine-Based Organic Photovoltaics

Mario C. Vebber et al.

Summary: Axially substituted silicon phthalocyanines [(R3SiO)(2)-SiPc] have shown potential as alternatives to fullerenes in organic photovoltaics (OPVs), with advances in molecular design and device fabrication leading to improved efficiencies. Factors such as the thermodynamic properties of SiPcs and blend morphology play crucial roles in determining device performance. Smaller critical radius values and higher Flory-Huggins miscibility parameter values have been found to correlate to higher power conversion efficiencies, with the properties being dependent on axial substituent size.

Fluoro-Substituted Metal Phthalocyanines for Active Layers of Chemical Sensors

Darya Klyamer et al.

Summary: Research on metal phthalocyanines with fluorine substituents as active layers of gas sensors has gained interest in recent decades, particularly focusing on their application as chemiresistive sensors. The introduction of fluorine substituents has been found to enhance sensitivity to reducing gases and enable some fluorinated phthalocyanine films to exhibit properties of n-type semiconductors.

Thin-Film Engineering of Solution-Processable n-Type Silicon Phthalocyanines for Organic Thin-Film Transistors

Rosemary R. Cranston et al.

Summary: This study investigated eight axially substituted SiPcs and their application in solution-processed n-type OTFTs. It was found that the length of the alkyl chain affects device performance and thin-film morphology, and the effects of high-temperature annealing and spin coating time on film formation were explored. The study also revealed that thermal annealing and spin time significantly impact film crystallinity, morphology, and device performance, with bis(tri-n-butylsilyl oxide) SiPc showing the highest electron field-effect mobility among the studied materials.

Silicon phthalocyanines: synthesis and resurgent applications

Koushambi Mitra et al.

Summary: SiPcs are distinct from other phthalocyanines due to their intense far-red absorption and emission features, as well as possessing two additional axial bonds that reduce aggregation in solution. Various synthetic strategies have been used to construct symmetrical or unsymmetrical SiPc variants with desired substituents, allowing for modulation of optical, chemical, and electronic properties.
