Since their initial discovery, numerous examples of these helices have been fabricated. In this contribution, the synthesis of a chiral, azobenzene (azo)\u2010containing isocyanide monomer is reported. Upon polymerization with nickel(II) catalysts, a well\u2010defined circular dichroism (CD) trace is obtained, corresponding to the formation of a right\u2010handed polymeric helix. The helical polymer, dissolved in chloroform and irradiated with UV light (365 nm), undergoes a <jats:italic>cis<\/jats:italic> to <jats:italic>trans<\/jats:italic> isomerization of the azobenzene side\u2010chains. After the isomerization, a change in conformation of the helix occurs, as evidenced by CD spectroscopy. When the solution is irradiated with LED light, the polymer returns to a right\u2010handed helical conformation. To open up the possibility for chain\u2010end post\u2010polymerization modification of this light\u2010responsive system, an alkyne\u2010functionalized nickel(II) catalyst is also used in the polymerization of the azobenzene monomer, resulting in a stimuli\u2010responsive, terminal\u2010alkyne\u2010containing helical poly(isocyanide).<\/jats:p>","DOI":"10.1002\/marc.201900324","type":"journal-article","created":{"date-parts":[[2019,8,27]],"date-time":"2019-08-27T13:31:50Z","timestamp":1566912710000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Synthesis and Light\u2010Mediated Structural Disruption of an Azobenzene\u2010Containing Helical Poly(isocyanide)"],"prefix":"10.1002","volume":"41","author":[{"given":"Scott K.","family":"Pomarico","sequence":"first","affiliation":[{"name":"Molecular Design Institute and Department of Chemistry New York University  100 Washington Square East New York NY 10003 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chengyuan","family":"Wang","sequence":"additional","affiliation":[{"name":"Molecular Design Institute and Department of Chemistry New York University  100 Washington Square East New York NY 10003 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6486-4268","authenticated-orcid":false,"given":"Marcus","family":"Weck","sequence":"additional","affiliation":[{"name":"Molecular Design Institute and Department of Chemistry New York University  100 Washington Square East New York NY 10003 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2019,8,27]]},"reference":[{"key":"e_1_2_4_1_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature06417"},{"key":"e_1_2_4_2_1","doi-asserted-by":"publisher","DOI":"10.7717\/peerj.619"},{"key":"e_1_2_4_3_1","doi-asserted-by":"publisher","DOI":"10.1021\/cr900162q"},{"key":"e_1_2_4_4_1","doi-asserted-by":"publisher","DOI":"10.1021\/cr0000978"},{"key":"e_1_2_4_5_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.chemrev.6b00354"},{"key":"e_1_2_4_6_1","doi-asserted-by":"publisher","DOI":"10.1039\/b710425a"},{"key":"e_1_2_4_7_1","doi-asserted-by":"publisher","DOI":"10.1021\/cr60276a001"},{"key":"e_1_2_4_8_1","doi-asserted-by":"publisher","DOI":"10.1021\/ja00825a038"},{"key":"e_1_2_4_9_1","doi-asserted-by":"publisher","DOI":"10.1039\/C0PY00246A"},{"key":"e_1_2_4_10_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature11839"},{"key":"e_1_2_4_11_1","doi-asserted-by":"publisher","DOI":"10.3390\/polym10050555"},{"key":"e_1_2_4_12_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.macromol.6b01410"},{"key":"e_1_2_4_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.201609103"},{"key":"e_1_2_4_14_1","doi-asserted-by":"publisher","DOI":"10.1021\/jacs.7b06201"},{"key":"e_1_2_4_15_1","doi-asserted-by":"publisher","DOI":"10.1039\/C8PY01361F"},{"key":"e_1_2_4_16_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsmacrolett.7b00875"},{"key":"e_1_2_4_17_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.199615541"},{"key":"e_1_2_4_18_1","doi-asserted-by":"publisher","DOI":"10.1021\/ma00152a005"},{"key":"e_1_2_4_19_1","doi-asserted-by":"publisher","DOI":"10.1039\/B701922J"},{"key":"e_1_2_4_20_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.macromol.5b02124"},{"key":"e_1_2_4_21_1","doi-asserted-by":"publisher","DOI":"10.1021\/ja039279k"},{"key":"e_1_2_4_22_1","doi-asserted-by":"publisher","DOI":"10.1039\/C6PY01881E"},{"key":"e_1_2_4_23_1","doi-asserted-by":"publisher","DOI":"10.1002\/cber.19600930720"},{"key":"e_1_2_4_24_1","doi-asserted-by":"publisher","DOI":"10.1021\/ja039279k"},{"key":"e_1_2_4_25_1","doi-asserted-by":"publisher","DOI":"10.1039\/c1cs15023e"},{"key":"e_1_2_4_26_1","doi-asserted-by":"publisher","DOI":"10.1039\/C4CY01597E"},{"key":"e_1_2_4_27_1","doi-asserted-by":"publisher","DOI":"10.1021\/cr00098a012"},{"key":"e_1_2_4_28_1","doi-asserted-by":"publisher","DOI":"10.1039\/C6TC02790C"},{"key":"e_1_2_4_29_1","doi-asserted-by":"publisher","DOI":"10.1021\/ma500254p"},{"key":"e_1_2_4_30_1","first-page":"581","volume":"28","author":"Yamada Y.","year":"2003","journal-title":"Trans.
