    • A series of nonpolar ortho-phenylene ethynylenes up to the hexamer has been synthesized. With chiral alkoxy substituents, no helical conformation in solution could be detected by means of circular dichroism spectroscopy, probably because of the short chain length and the potentially destabilizing effect of donor substituents on π-π stacking; see Jones, T. V.; Blatchly, R. A.; Tew, G. N. Org Lett 2003, 5, 3297.

    • Because of GPC calibration with polystyrene standards, the measured absolute molecular weights are associated with a certain error. Although no experimental proof can be given at this time, we believe that because of their ortho connectivity, PoPEs are rather compact, and hence the molecular weights should not substantially be overestimated as in the case of PpPEs [poly(para-phenylene ethynylene)s] (see ref. 17).
