The book entitled 'Organic Light Emitting Materials for OLEDs' covers both the theoretical and practical aspects of the chemistry and properties of organic materials and emphasis mostly on the materials based on dibenzophospholes and phosphine oxides. The introduction and the aim of each chapter is given at the start of the chapter. The subject matter has been presented in a very simple language, clear style along with a number of illustrative diagrams where required. As an Author, I personally believe that this book will definitely deliver all necessary information for the benefit of students and researchers in the field of organic electronics.
