Discotic liquid crystals of transition metal complexes 56: Synthesis of mesogenic phthalocyanine-fullerene dyads and influence of the substitution position of alkoxy chains and the kind of terminal groups on appearance of the helical supramolecular structure

Autor: Ayumi Watarai, Mikio Yasutake, Kohei Ishikawa, Kazuchika Ohta

Publikováno v: Journal of Porphyrins and Phthalocyanines. 22:693-715

We have synthesized twelve novel discotic columnar liquid crystals based on a phenoxy-group-substituted phthalocyaninato copper(II) complex having the same alkoxy chain of C[Formula: see text]H[Formula: see text]O at different positions in the phenox

Discotic liquid crystals of transition metal complexes 52: Synthesis and homeotropic alignment of liquid crystalline phthalocyanine-fullerene dyad bridged by vanillin

Autor: Kazuchika Ohta, Mikio Yasutake, Ayumi Watarai

Publikováno v: Journal of Porphyrins and Phthalocyanines. 20:1444-1456

We have synthesized a novel liquid crystalline phthalocyanine(Pc)-fullerene(C-60) dyad (C14S)(6)PcCu-VAN-C-60 (3a) bridged by an inexpensive natural product of vanillin (VAN), instead of the previous long n-alkylene chain spacer. We have also synthes

Flying-seed-like mesogens 6: Synthesis and mesomorphism of phthalocyanine derivatives substituted by pentafluorosulfanylphenoxy group

Autor: Kazuchika Ohta, Ayumi Watarai, Mikio Yasutake

Publikováno v: JOURNAL OF PORPHYRINS AND PHTHALOCYANINES. 20(7):822-832

We have synthesized two novel phthalocyanines, (m-SF5PhO)(8)PcCu (7b) and (p-SF5PhO)(8)PcCu (7c), in order to investigate their flying-seed-like mesomorphism. Their phase transition behavior and the mesophase structure have been established by using

Liquid Crystals of Phthalocyanine-Fullerene Dyads Exhibiting Homeotropic Alignment and Spiranthes-like Supramolecular Structure Useful for Solar Cells

Autor: Ayumi Watarai, Kenta Ono, Aya Ishikawa, Shin-nosuke Yajima, Mikio Yasutake, Kazuchika Ohta

Publikováno v: ECS Transactions. 66:21-43

A homologous series of the phthalocyanine-fullerene dyads, (CnS)6PcCu-Cm-C60 (4a~g) [(n, m) = (14, 8) (a); (14, 10) (b); (14, 12) (c); (16, 8) (d); (16, 10) (e); (16, 12) (f); (18, 10) (g)], have been synthesized with changing both the chain length o

Liquid Crystals of Phthalocyanine-Fullerene Dyads Exhibiting Homeotropic Alignment and Spiranthes-like Supramolecular Structure Useful for Solar Cells

Autor: Ayumi Watarai, Aya Ishikawa, Kenta Ono, Mikio Yasutake, Kazuchika Ohta

Publikováno v: ECS Meeting Abstracts. :1001-1001

If liquid crystals of phthalocyanine-fullerene (Pc-C60) dyads would exhibit homeotropic alignment at r.t., they would be very useful for the application to solar cells. Hence, we have synthesized nine novel Pc-C60 dyads, (CnS)6PcCu-Cm-C60 (n = 14, 16
