Abstract

Abstract New routes to ladder-type phenylene materials 1 and 2 are described. The oligomers 1 and 2, which possess a “3π-2spiro” architecture, have been synthesized by using extended diketone derivatives 3 and 10 as key intermediates. The physicochemical properties of the new blue-light emitter 2 were studied in detail and compared with those of the less-extended 1. Owing to the recent development of fluorenone derivatives and their ...
