AbstractSpin-coated 52-nm-thick films of newly synthesised gadolinium liquid crystalline bisphthalocyanine sandwich (GdPc2) complexes with octyl chains non-peripheral positions have been successfully employed as active layers for bottom-gate organic field effect transistors having both short $$(5\,\upmu {\text{m}})$$(5μm) and long $$( 20\,\upmu {\text{m}})$$(20μm) channels. The scaling down of the channel length $$( L )$$(L) decreases the field effect mobility due to the increase in the contact resistance between the gold electrodes and the GdPc2 semiconducting layer. Values of on–off ratio and sub-threshold voltage swing are higher nearly one order of magnitude for $$L = 5 \,\upmu{\text{ m}}$$L=5μm than those for $$L = 20\;\upmu m$$L=20μm.

Thiophene oligomers end-capped with phenyl-1H-pyrrole were used as active layers of organic field-effect transistors. Two types of cores that vary in size and shape of α-linked thiophenes and fused-ring thiophenes were chosen to study the structure–property relationship. The crystal structures, optical, electrochemical and electronic properties were investigated, and the heterocyclic compounds exhibited clear p-type semiconducting behavior.
