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.
