Photochemical switching of polarization in ferroelectric liquid-crystal films

TL;DR: In this article, a photochemical process was used to induce spontaneous polarization switching in ferroelectric liquid crystals driven by photochemical processes, where the liquid-crystal films are doped with a photochromic compound which undergoes trans-cis isomerization on irradiation.
Journal ArticleDOI

Photochemical control of properties of ferroelectric liquid crystals : photochemical flip of polarization

TL;DR: In this paper, a photochemical control of optical properties of ferroelectric liquid crystal (FLC) is presented, which is based on photochemically induced switching of polarization of FLC triggered by photoisomerization of azobenzene derivatives doped in FLC.
Journal ArticleDOI

Photoisomerization and thermal isomerization behavior of azobenzene derivatives in liquid-crystalline polymer matrixes

TL;DR: In this paper, the inner free volume of the PLC matrices of azobenzene derivatives molecularly dispersed in liquid crystal polyacrylates (PLC) [CH 2 CH(COOR)] n (R= (CH 2 ) n OPhCOOPhOMe n= 3,6) was investigated with reference to the inner-free volume.
Journal ArticleDOI

"Intrinsic" response of polymer liquid crystals in photochemical phase transition

TL;DR: Time-resolved measurements were performed on the photochemically induced isothermal phase transition of polymer liquid crystals (PLC) with mesogenic side chains of phenyl benzoate (PAPB3) and cyanobiphenyl (PACB3), under conditions wherein the photochemical reaction of the doped photoresponsive molecule (4-butyl-4-{prime}-methoxyazobenzene, BMAB) was completed within {approximately} 10 ns, and the subsequent phase transition from the matrix PLC from nematic (N
