In our group, we have focused on a unique alkynylborane compound "dimesitylborylethynylanthracene (1A)", in which the dimesitylboryl group and the 9th position of the anthracene ring are bridged by an ethynediyl group, and revealed its optical and electron-transporting properties. In this study, we investigated the electron and hole mobilities in amorphous films of 1A and its derivatives (1A2Ph, 1A10Ph), which have a phenyl group introduced at the 2nd or 10th position of the anthracene ring of 1A, by the time-of-flight (TOF) method.
