Abstract

Nitric oxide (NO) is an essential redox-signaling molecule free radical, contributes a significant role in a diverse range of physiological processes. Photo-triggered NO donors have significant potential compared to other NO donors because it releases NO in the presence of light. Hence, an efficient visible light-triggered NO donor is designed and synthesized by coupling 2,6-dimethyl nitrobenzene moiety at the peri-position of 1, 8-naphthalimide. The NO-releasing ability is validated using various spectroscopic techniques, the photoproduct is characterized, and finally, the NO generation quantum yield is also determined. Furthermore, the photo-generated NO has been employed to Arabidopsis thaliana as a model plant to examine the effect of photoreceptor-mediated NO uptake on plant root growth regulation molecule.
