Solution-Processable Indenofluorenes on Polymer Brush Interlayer: Remarkable N-Channel Field-Effect Transistor Characteristics under Ambient Conditions.

ABSTRACT: The development of solution-processable n-type molecular semiconductors that exhibit high electron mobility (μ_e ≥ 0.5 cm²/(V·s)) under ambient conditions, along with high current modulation (I_on/I_off ≥ 10⁶-10⁷) and near-zero turn on voltage (V_on) characteristics, has lagged behind that of other semiconductors in organic field-effect transistors (OFETs). Here, we report the design, synthesis, physicochemical and optoelectronic characterizations, and OFET performances of a library of solution-processable, low-LUMO (-4.20 eV) 2,2'-(2,8-bis(3-alkylthiophen-2-yl)indeno[1,2-b]fluorene-6,12-diylidene)dimalononitrile small molecules, β,β'-C_n-TIFDMTs, havin
