Photoisomerization Kinetics of a Novel Photoswitchable Film Based on Methyl Red Doped with Sodium Hexachloroplatinate Hosted in Polyethylene Oxide

This work proposes a novel dopant material to improve the energy storage in azo molecules. Organometallic material with platinum base atom (sodium hexachloroplatinate (IV) (Na2PtCl6)) was used as a dopant material in polyethylene oxide-methyl red (PEO-MR) films. The photoisomerization kinetics, the energy storage, and the electrical conductivity distribution of PEO-(MR-Na2PtCl6) films are investigated and studied. In addition, the effect of Na2PtCl6 on the chemical and crystal structure is also premeditated. It can be concluded that adding Na2PtCl6 to PEO-MR film improves the energy storage in the azo molecules. Therefore, the addition of Na2PtCl6 into PEO-MR films can be proposed for different applications, especially in molecular solar thermal energy storage media.
