5-Hexylthiophene-fused porphyrazines were designed and synthesized as novel soluble phthalocyanine derivatives. Single-crystal X-ray structural analyses indicated that they have a well-ordered structure in the solid state in spite of the existence of disorder in the thiophene-fused porphyrazine core. Due to the high solubility and improved molecular ordering, the present 5-hexylthiophene-fused porphyrazines showed comparable performance to vapor-processable phthalocyanines as solution-processable organic semiconductors: solution-processed OFETs showed mobility of up to 0.2 cm 2 V-1 s-1.
