Abstract
7,16-Dihydroheptacenes (1-3) substituted at the 6, 8, 15, and 17 positions are synthesized as blue emitters potentially useful in organic light emitting diodes (OLEDs). The photophysical properties of 1-3 (lambda(max) = 424-428 nm, phi(F) = 0.15-0.21, tau(F) = 2.35-2.67 ns in CH2Cl2) are discussed. They are shown to be stable and efficient blue emitters in the solid state (phi(F) = 0.37-0.44). The X-ray crystal structure of 1 is reported.
