摘要:
The polycycloaddition of azomethine ylides to dipolarophiles is described for the first time. Use of (cis,cis)-bis-aziridines as a source of azomethine ylides allows selective polyaddition to be realized, which leads to oligomers exclusively with trans-substituted pyrrolidine rings and modest molecular weights (ca. 5-10 kDa). The fluorescent, electrochemical, electrochromic, and non-linear optical properties of the main-chain free-base porphyrin oligomer, synthesized by the developed procedure, are studied. An enhancement of the optical power limiting effect in a porphyrin oligomer solution is registered against that of the monomer. <boxed-text content-type="graphic" position="anchor"> <graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="urn:x-wiley:10221352:media:macp201300679:macp201300679-abs-0001">image</graphic
