and steric bulk. When used in SCLC devices, compound 1 exhibits a high hole mobility value of 8.84 cm2/V.s at ambient temperature whereas compounds 2 and 3 show efficient ambipolar charge transport behavior with maximum hole (h) and electron mobility (e) of 0.70 cm2/V.s and 3.59 cm2/V.s, respectively, for compound 3. The mobility values (h = 8.84 cm2/V.s for 1 and e = 3.59 cm2/V.s for 3) are remarkable
Guanidinium minidendrons bearing terminal aliphatic chains show a columnar liquid-crystalline behaviour once associated with chlorine anions, whereas they turned into layered phases when associated with phosphorescent octahedral molybdenum cluster dianions. The emission properties of the inorganic dyes are largely influenced by the minidendron chain length in these first-of-their-kind clustomesogens
