The crystal structure of an endoperoxide of tetrabenzo[de,hi,op,st]pentacene (TBPA-O-2) was determined by X-ray crystallography. The unusually long O-O and C-O bonds were rationalized by the characteristic molecular structure of TBPA-O-2. The photochromic behavior between TBPA-O-2 and TBPA was discussed based an the enthalpy difference between TBPA-O-2 and TBPA + O-2 and the thermodynamic parameters of the extrusion reaction of oxygen from TBPA-O-2.

Two new anthracene derivatives with red emission have been synthesized. The materials were characterized with photoluminescence spectroscopy, and showed emission peaking at over 600 nm. Organic light-emitting devices were fabricated by using these derivatives as dopants. The devices have a maximum efficiency of 0.6 cd A−1 and an emission peak at 617 nm. The results of color tuning and fluorescent yield enhancement for anthracene derivatives are presented.
