Abstract:
Spin-coated 52-nm-thick films of newly synthesised gadolinium liquid crystalline bisphthalocyanine sandwich (GdPc 2 ) complexes with octyl chains non-peripheral positions have been successfully employed as active layers for bottom-gate organic field effect transistors having both short $$(5\,\upmu {\text{m}})$$ ( 5 μ m ) and long $$( 20\,\upmu {\text{m}})$$ ( 20 μ m ) 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 GdPc 2 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 = 5 μ m than those for $$L = 20\;\upmu m$$ L = 20 μ m .
