Abstract:
During past few years, significant attention has been paid to the chemistry of azo linked
Schiff bases due to important chemical moiety and their extensive multidisciplinary
applications, optical properties, used in high performance organic light emitting diodes
(OLEDs), bio diagnostic tools and conductor-based sensory devices. Due to nonbiodegradability
and high-risk effects of heavy metals on human health and environment,
detection of these metals is of extreme interest. For this purpose, chelation and selectivity of
synthetic compounds with metal is important due to presence of active donor sites as these
cost-effective azo linked Schiff bases can selectively detect metals through change in color
intensity. In present research work, novel azo linked Schiff bases have been synthesized,
characterized by spectroscopic techniques. Metal sensing ability has been determined by
using azo linked Schiff based liquid crystal sensor and biological screening of synthesized
compounds have also been evaluated
