Currently, hundreds of articles about OLED materials are published every year . There are a lot of useful data in the literature, but there is no existing database that organizes OLED material data. With the aims of archiving the thermal stability data of OLED materials and helping experimental scientists utilize the models reported in this paper for designing new OLED compounds with desired Tg and Td values, an online tool was developed. This website is accessible at . Users can make predictions by inputting canonical SMILES, and the outputs include Tg (K) and Td (K).
