Phenothiazine is a butterfly shaped molecule based on indoline use as a starting material to synthesis organic dyes. These dyes have significant properties and performance in optoelectronic devices. Many optical and electrical properties such as photoluminescence, electroluminescence and electro-chemical properties can be modified by placing appropriate moiety on the parent phenothiazine group. In the last few decades, these electro- and photo-sensitive dyes have provided wide range of applications. This article presents the latest report on the development of small to medium sized phenothiazine-based dyes for dye sensitized solar cells, organic light emitting diodes, nonlinear optical materials, hole transporting components and sensors. For this end, an attempt structure properties and molecular design to improve these application and to test landscape perspective.
