a Schematic illustration of molecular packing and TDM direction in the BPCBT microwire. b POM images of two crossed microwires. The arrows indicate the direction of optical polarizers. c Absorption and photoluminescence spectra of the dilute solution (red) and the microwire (blue) of BPCBT. Excitation wavelength in photoluminescence measurement is 400 nm. d Photoluminescence decay curves from the BPCBT solution and the microwires. Excitation and emission wavelengths are 400 and 585 nm, respectively.
