Description and Uses

NitroBIPS is used as a photochromic dye which can be incorporated in poly(vinylalcohol)(PVA) by electro-spinning to form PVA-spiropyran nanofibres. It has photo-responsive behaviour that may be useful in optical data storage applications. It can be used to dope liquid crystal to develop a coloured scattering device that is dual responsive and allows the initiation of electrohydrodynamic instabilities(EHDI). Addition of NitroBIPS can modify the transparency from 100% to 16%, providing a shielding effect which can be used for smart window applications. It may also be used to enhance the adhesion property of polystyrene(PS) on the glass substrate by improving the shear strength by a factor of 7.
