Abstract:	In this work, “isobutrin”, an ecofriendly sensitizer that is extracted from Butea monosperma (commonly known as “Flame of the Forest”) flowers, is introduced. It is a bright yellow pigment belonging to the chalcone class and is examined as a sensitizer for optoelectronic applications. It is observed that chelation of this dye with Ti ions results into a strong dye-TiO2 charge transfer (DTCT) band in the visible region. This Ti-Isobutrin chelate is stable, irreversible and its formation is studied using Benesi–Hildebrand plot. The locations of HOMO–LUMO states of the Ti-isobutrin chelate and the corresponding band alignment with TiO2 are obtained. Also, a thermal stability test revealed that isobutrin is stable above 100 °C.
