Abstract

The crude extract of eight specimen leaf samples were studied by phytochemical analysis for investigating prospects of the extracts for environmentally-friendly dye compounds that could be useful for smart windows. The phytochemical analysis reveals the presence of phytoconstituents such as flavonoids, anthraquinones, tannins, saponins, thus suggesting presence of compounds that could be useful as dye for smart windows in the chromophore of the plant. As a preliminary test, dye pigment grown on glass from the extracts, using the Solution Growth Technique, exhibited low absorbance and high reflectance at transmittance set at 400 nm when studied using UV/VIS spectroscopy between 190 nm and 1100 nm wavelength i.e. within the visible range of light in the electromagnetic spectrum. These indicated suitability of the leaf-extracts from the studied plants for growing environmentally-friendly dye compounds that could be used for smart windows.
