Guest–host interaction of some aminoazobenzene dyes doped in liquid crystalline matrix

Role of specific and nonspecific intermolecular interaction in electro-optical response of doped 6CHBT nematic liquid crystal with azo dyes

“…These dyes (A and B dyes) have a rod like shape and the direction of the dipole moment of them is largely parallel to the long molecular axis [4].…”

“…Enhancement of the electro-optical properties of liquid crystal is dependent on the type, concentration and intrinsic characteristics of the dopants used [1][2][3]. Generally, various kinds of guest-host systems are used to enhance their optical and electro-optical properties and improve the performance of optoelectronic devices [4][5][6][7][8]. The linear and nonlinear optical properties of the host material can be affected considerably, by doping with a small amount of dye [9][10][11][12][13].…”

Alignment and Reorientation in Nematic Liquid Crystals Doped with Red Dye and Carbon Nanotube

“…The composition of E63 is similar to E7. However, it also contains cyclohexane and ester components in low percentages, in addition to biphenyl-terphenyl weighted structure in E7 (2,(13)(14)(15).…”

“…One of the most important applications is liquid crystal displays (LCDs) using guest-host interaction (1,2). They use an alignment of LC (host) under electric voltage and the close reorientation of the dye (guest) dissolved.…”

Substituent and solvent effects on the dipole moments and photophysical properties of two azo sulfonamide dyes

“…Their elongated molecular structures and large order parameter in liquid crystalline media, give them potential for application in non-linear optical (NLO) devices [3,4]. Many studies have been dedicated to investigate the relationship between the structure and the spectroscopic features of azo dyes [4][5][6][7][8][9]. Azo sulfonamide derivatives with heteroaromatic substituents are able to demonstrate NLO behavior in thin layers [10].…”
