Amorphous molecular materials: synthesis and properties of a novel starburst molecule, 4,4',4''-tri(N-phenothiazinyl)triphenylamine: Amorphous molecular materials: synthesis and properties of a novel starburst molecule, 4,4',4''-tri(N-phenothiazinyl)triphenylamine. Higuchi, Akiji; Inada, Hiroshi; Kobata, Tomokazu; Shirota, Yasuhiko (Fac. Eng., Osaka Univ.In this study， 139417-53-1 and 4181-20-8 are also used., Osaka 565, Japan). Adv. Mater. (Weinheim, Fed. Repub. Ger.), 3(11), 549-50 (English) 1991. CODEN: ADVMEW. ISSN: 0935-9648. DOCUMENT TYPE: Journal CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) The title compd. I, a novel starburst mol. consisting of a p-electron system, was synthesized with the aim of developing amorphous mol. materials having high glass-transition temps. The material shows unique solid-state morphol.; it readily forms a stable amorphous glassy state with a glass-transition temp. as high as 141°, as characterized by differential scanning calorimetry and x-ray diffraction. Pellet samples of I doped with iodine exhibit room-temp. conductivities up to 10-2 S cm-1. .

DOCUMENT TYPE: Patent CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Section cross-reference(s): 74, 76 The title compd. (I), which show amorphous state at ordinary temp. and is easy to be made into thin film for photoelec. converters, thermochromic devices, optical memory devices, etc., is prepd. A mixt. 4181-20-8 and 139092-78-7 are also in the experiment. of 4,4',4''-triiodotriphenylamine, carbazole, KOH, Cu, and decalin was stirred at 170° for 10 h to give 10.5% I. I was heated to the m.p. then cooled to the glass transition temp. to form a stable amorphous state. .
