Blue light-emitting anthracene-based host materials with a spiro [benzo [c] fluorene-7, 9′- fluorene] core, 5-(10-(naphthalen-2-yl) anthracen-9-yl) spiro [benzo [c] fluorene-7, 9′- fluorene](NA-SBFF) and 5-(10-(4-(naphthalen-1-yl) phenyl) anthracen-9-yl) spiro [benzo [c] fluorene-7, 9′-fluorene](NPA-SBFF), were designed and synthesized via two-step Suzuki coupling reactions. Introduction of a spiro group into the structure of the anthracene ...
