Development of novel symmetrical and asymmetrical alkyne-functionalized silicon phthalocyanines, a potential functionality control for organic semiconductors

Metal phthalocyanines offer a wide variety of chemical modifications that can be exploited to tailor the material properties to target different applications. This work demonstrates the electrochemical and optical fine-tuning of silicon phthalocyanine (SiPc) derivatives by introducing axial asymmetry. When integrated into organic thin-film transistors (OTFTs) as organic semiconductors, the studied asymmetric derivatives exhibit modest [Formula: see text]-type performance relative to symmetrical
