J-aggregation of photochromic spiropyran in Langmuir-Blodgett films
TL;DR: In this article, the possibility of controlling the photochromic reactions of two different spiropyrans was investigated using the Langmuir-Blodgett technique, and the most stable monolayer was formed on mixing with n-octadecane in a molar ratio of 1:2.
Journal ArticleDOI
Monolayers and multilayers of anthraquinone derivatives containing long alkyl chains
TL;DR: In this paper, the surface films of anthraquinone derivatives with long alkyl chains have been investigated and it has been concluded that different types of orientation of the anthrasquone nuclei can be realized in the surface film of these long-chain dyes, depending on the chemical modifications, such as variation in the numbers and relative positions of the long substituent groups, and also on the physical conditions for deposition.
Journal ArticleDOI
Ultraviolet photoemission study of oligothiophenes: π-band evolution and geometries
H. Fujimoto,Umpei Nagashima,Hiroo Inokuchi,Kazuhiko Seki,Y. Cao,Hiroo Nakahara,Juzo Nakayama,Masamatsu Hoshino,Kiyoshige Fukuda +8 more
TL;DR: In this article, a series of α-linked oligomers (αn with n being the number of rings) with 4-8 thiophene rings were used to investigate the electronic structure of oligothiophenes.
Journal ArticleDOI
Photoisomerization of the azobenzenes included in Langmuir-Blodgett films of cyclodextrins☆
Akira Yabe,Yasujiro Kawabata,Hiroyuki Niino,Mutsuyoshi Matsumoto,Akihiko Ouchi,Hisao Takahashi,Shoji Tamura,Waichiro Tagaki,Hiroo Nakahara,Kiyoshige Fukuda +9 more
TL;DR: In this paper, a new type of photochemical Langmuir-Blodgett (LB) film containing azobenzenes (p-phenylazobenzoic acid (PAB), methyl red (MR) and methyl orange (MO)) without long alkyl chains was prepared by the host-guest interaction with an amphiphilic cyclodextrin derivative.
Journal ArticleDOI
Studies on molecular orientation in multilayers of long-chain anthraquinone derivatives by polarized infrared spectra
Hiroo Nakahara,Kiyoshige Fukuda +1 more
TL;DR: In this article, the orientation of the chromophore in the built-up multilayers has been investigated by angular dependence of the polarized infrared spectra, and it has been found that the long alkyl chains have a tendency to orient depending not only on the vertical direction to the water surface but also on the direction of monolayer compression in the 2D plane.
