✦ Synopsis

We have developed the first multifunctional organic material, 4,4 0 ,4 00 -tris(4-naphthalen-1-ylphenyl)amine (1-TNPA), which can be used as a deep blue emitting and hole-transporting material in organic light-emitting diodes (OLEDs), as a donor material in organic solar cells (OSCs), and as an active material in organic thin-film transistors (OTFTs). In particular, in the case of 1-TNPA-based OLEDs, efficient emission characteristics, the emission of deepblue light similar to the National Television Standard Committee (NTSC) standard blue, and more efficient hole transport than that in the case of NPD-based OLEDs were observed. 1-TNPA can be also used as a donor in OSCs and as an organic semiconductor in OTFTs.
