Photoresponsive Nano-Coumarin with Indole Auxin Hormone

Abstract:

In this work, we designed and synthesized two photoresponsive materials with 3-indoleacetic acid (IAA) plant hormone which can be monitored from the photoreposive properties of coumarin. The varied position of the long alkoxy side chain (-OC₁₆H₃₃) was purposely introduced to adhesive on the plant leaves. Two coumarin-caged nanomaterials showed average particle diameter about 400 nm and gave the maximum emission wavelength at 425 and 450 nm. The formulated nanoemulsion showed good wettability (θ=48^o) with Cassia fistula leave surface. Interestingly, CM2 gave the short photoresponse of photolysis within one day.
