Abstract

Jae-Suk Lee, Takhee Lee, and co-workers investigate on page 385. structural and electrical characteristics of synthesized block copolymers consisting of poly(9-(4-vinylphenyl)carbazole)-b-poly(2-vinylpyridine) Various morphologies such as spherical or lamellar structures with microphase separation are obtained. In particular, devices with a lamellar structure exhibited memory switching, which is strongly related to the formation and rupture of highly conductive paths consisting primarily of carbazole segments.
