General description

N-(4-Methoxybenzylidene)-4-butylaniline (MBBA) is a nematic liquid crystal molecule that can be prepared by condensing distilled n-butylaniline and methoxybenzaldehyde. It can be used as an anisotropic solvent which has an isotropic transition temperature of 315k. It is majorly used in the development of liquid crystal cells.

The birefringence of MBBA, determined from the channeled spectra, decreases when the wavelength increases, showing a normal dispersion. The changes induced by an external electrostatic field acting perpendicular on the nematic director in the birefringence values were evidenced. The birefringence
