Abstract

Developing new organic conjugated materials for high density memory devices is highly desirable. In this research, a novel donor–acceptor-type twelve-ring fused twistheteroacene, 2,7,19,24-tetra-tert-butyl-13,30-didodecyl-9,17,26,34-tetraphenyl benzo[8′,9′]triphenyleno[2′,3′:7,8]dibenzo[b,e][1,4]dioxino[1,2,3,4-lmn]dibenzo[6′,7′:10′,11′]tetraceno[2′,3′:5,6][1,4]dioxino[2,3-f][3,8]phenanthroline-12,14,29,31(13H,30H)-tetraone (DPyN) has been synthesized and characterized. It displays high thermal stability, possesses a broad absorption band centered at 510 and 538 nm, and emits red fluorescence in organic solvents. A solution-processed memory device with DPyN as an active element shows an excellent memory performance with an ON/OFF current ratio of 103.46:1 and a threshold voltage of −2.44 V.
