Highlighting the processing versatility of a silicon phthalocyanine derivative for organic thin-film transistors

Silicon phthalocyanine (SiPc) derivatives have recently emerged as promising materials for n-type organic thin-film transistors (OTFTs) with the ability to be fabricated either by solid state or solution processes through...

Axially-substituted silicon phthalocyanine payloads for antibody-drug conjugates

IR700, a silicon phthalocyanine (SiPc) photosensitizer, is an antibody-drug conjugate payload used clinically. It is, however, the sole SiPc payload to date, possibly due to the difficulty of its synthesis, resulting from its asymmetric phathalocyanine skeleton. Here we report a new axially-substituted SiPc payload with easier synthesis. Trastuzumab conjugated with the SiPc showed light- and antigen-dependent cytotoxicity in HER2-overexpressed cancer cell lines.

Attaining air stability in high performing n-type phthalocyanine based organic semiconductors

The perfluorinated analogue of silicon phthalocyanine (F2-F16SiPc) has been synthesized as a novel air-stable n-type organic semiconductor. The design of F2-F16SiPc facilitates strong electron conduction through peripheral fluorination that deepens...
