Spiro-Linked Hyperbranched Architecture for Electrophosphorescent Polymers

Part of the Springer Theses book series (Springer Theses)


Introducing phosphorescent emitters into polymers to harvest both singlet and triplet excitons in the EL process has been proved to be an effective approach to enhance the device efficiency [1, 2, 3, 4, 5, 6]. To ensure that all the triplet excitons are confined effectively on the phosphorescent emitters, triplet energy back transfer (TEBT) from phosphors to polymer hosts should be inhibited (see Sect. 1.3 in Chap.  1)
