2005 journal article

Chiroptical switching polyguanidine synthesized by helix-sense-selective polymerization using [(R)-3,3 '-dibromo-2,2 '-binaphthoxy](di-tert-butoxy)titanium(IV) catalyst

JOURNAL OF THE AMERICAN CHEMICAL SOCIETY, 127(7), 2136–2142.

By: H. Tang n, P. Boyle n & B. Novak n

TL;DR: Interestingly, poly-1b was found to undergo fast reversible chiroptical switching at +38.5 degrees C in toluene, and this is the first example of chiroPTical switching phenomenon occurring in a helical polymer possessing no chiral moieties in the polymer chains. (via Semantic Scholar)

2004 journal article

Stable helical polyguanidines: Poly{N-(1-anthryl)-N '-[(R)- and/or (S)-3,7-dimethyloctyl]guanidines}

JOURNAL OF THE AMERICAN CHEMICAL SOCIETY, 126(12), 3722–3723.

By: H. Tang n, Y. Lu n, G. Tian n, M. Capracotta n & B. Novak n

TL;DR: Using chiral catalysts of (R)- and/or (S)-BINOL-Ti, the asymmetrical polymerization of achiral monomer, N-(1-anthryl)-N'-n-octadecylcarbodiimide, yielded soluble nonregioregular polyguanidines of Poly-R1 and Poly-S1. (via Semantic Scholar)
