In this study, a C-3-symmetric star-shaped discotic mesogen has been reported, exhibiting high electron mobility and significant potential for use in organic electronic devices.
In this study, a C-3-symmetric star-shaped discotic mesogen has been reported based on an electron-deficient tris(triazole) central rigid core functionalized with three peripheral trialkoxyphenyl units. The mesogen exhibits an enantiotropic columnar hexagonal (Col(h)) phase that can sustain over a significant temperature range. When used in space-charge limited current (SCLC) devices, it showed ambipolar charge transport behavior with high electron mobility (mu(e)) of 1.61 x 10(-2) cm(2) V-1 s(-1) at ambient temperature. The finding is sufficiently significant to warrant their use in organic electronic devices.
