A new synthetic method for triazatruxenes from indoles is developed using N-bromosuccinimide (NBS) as a user-friendly reagent. Major reaction parameters including the amount of NBS, substrate concentration, temperature, addition rate and addition method are investigated. Additional experiments are also conducted in order to gain access toward the reaction mechanism. Compared to the use of Br2 in the

Hole-transport is an important process in electronic devices such as organic field-effect transistors (OFETs) and organic light-emitting diodes (OLEDs). However, the molecular structures required for hole-transporting materials in OFET and OLED applications are quite different. In this paper, we examined the effect of alkylation onto a disk-like shaped molecule both in OFET and OLED devices. While
