Selenium-containing bodipy dyes as photosensitizers

Abstract

“Boron-dipyrromethenes or BF2dipyrrins (BODIPY)“ are high fluorescent dyes and it is applicable in many fields for their attractive photochemical and photophysical properties. BODIPY has different sites of potential for its functional groups, where these groups can be functionalized and introduced. BODIPY can help in building blocks for the synthesization of the desired derivatives of BODIPY. The paper presents a series of existing literature on the given topic to obtain the required information for further studies. It presents that BODIPY could be utilized to wash the living cells for sensing the temperature and fluorescence imaging, in addition to that it also presents an increase of water solubility for increasing the efficiency. Different methods are utilized for the preparation of Selenium BODIPY, 2–1 pot procedure that follows the DDQ oxidation process. One of the most commonly used approaches for synthesis is the pyrrole condensation with aldehydes and the reaction within it is performed with the help of chromatography. BODIPY dyes are able to note their absorption band and stoke shifts for functionalized polymers for systems for light harvesting in solar cells. The dyes holds fluorescence molecules with relevant chemical and physical characteristics for both thermal and chemical stabilities. The substance possess low polarity and pH elements with low sensitivity and PDT as a photosensitizer. The applications of BODIPY hold sharp absorption and visible fluorescence, easy to use synthetization, ”high absorption coefficient“, and stable chemical and thermal properties. Lastly, it can be seen that BODIPY are able to produce dyes quickly and easily.
