Two novel anthracene derivatives with an spiro [ benzo[ c ] fluorene -7,9 0 -fluorene ~ core structure, NA- SBFF and NPA- SBFF, were designed and synthesized as high fluorescent deep blue host materials with good thermal stability and the physical properties. In this paper, their structures and properties of charge transport and spectra were studied by quantum - chemical methods. The results show that the theoretical analysis is in agreement with the experimental results. They have spiro -type structures, good thermal stabilities, similar charge injection or transfer properties, wide energy gaps, and highly efficient blue light emission. And so the two compounds have great potential for fluorescent OLEDs applications.
