摘要：
Making the shift: The title reaction of a propargylic bis(carbonate) with diboron compounds leads to new cross-conjugated polymers 1 having 2,3-butadienylene moieties. 1 is then converted into the linear-conjugated polymers 2 through a Diels-Alder reaction. The fluorescent spectra of the cis-linked polymers 2 show large Stokes shifts compared to those of the cross-conjugated polymer precursors 1. © 2012 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
