POLYARYLENES AND POLYARYLENEVINYLENES .2. OLIGORYLENE AS A MODEL FOR POLY(PERINAPHTHALENE)

Rylenes are annelated arenes derived formally by coupling all the peri‐positions of naphthalene. Several soluble oligorylenes have now been synthesized as models for “polyrylene” 1. R = H. Among the most striking features to emerge in the course of characterizing the compounds were a small HOMO/ LUMO energy gap for the quaterrylene 2, R = tBu, n = 2. and a high powder conductivity for the charge‐transfer complex of the same compound.
