a, UV–vis absorption spectra of 2DPI-BTT-P (light violet), 2DPAV-BTT-P (dark red), 2DPAV-BTT-P(Kn) (dark cyan), 2DPI-BTT-BP (black), 2DPAV-BTT-BP (olive) and 2DPAV-BTT-BP(Kn) (cyan). b, Time-resolved terahertz photoconductivity of 2DPAV-BTT-P (dark red), 2DPAV-BTT-P(Kn) (dark cyan), 2DPAV-BTT-BP (olive) and 2DPAV-BTT-BP(Kn) (cyan). c, Frequency-resolved complex terahertz photoconductivity for 2DPAV-BTT-BP. The solid blue and red lines represent the Drude–Smith fits describing the real and imaginary components of the complex terahertz photoconductivity, respectively. d, Comparison of charge carrier mobilities and electrical conductivities of 2DPAV-BTT-BP, amorphous 2DPAV-BTT-BP(Kn) and 2DPI-BTT-BP.
