Proton exchange and base-pair kinetics of poly(rA) · poly(rU) and poly(rI) · poly(rC)

Journal of Molecular Biology, 1985
Proton exchange of poly(rA).poly(rU) and poly(rI).poly(rC) has been studied by nuclear magnetic resonance line broadening and saturation transfer from H2O. Five exchangeable peaks are observed. They are assigned to the imino, amino and 2'-OH ribose protons. The aromatic spectrum is also assigned.

The helix–coil transitions of poly (dA). Poly (dT) and poly (dA‐dT). Poly (dA‐dT)

Biopolymers, 1972
AbstractHelix–coil transition curves are calculated for poly (dA) poly(dT) and poly (dA‐dT) poly (dA‐dT) using the integral equation approach of Goel and Montroll.5 The transitions are described by the loop entropy model with the exponent of the loop entropy factor, k, remaining an arbitrary constant.

Novel extended donors: Poly(peri-naphthylenes), poly(tetrathiafulvalenes), poly(arylenevinylenes)

Synthetic Metals, 1991
Abstract Novel conjugated polymers are synthesized and the correlation between structure and physical properties is elucidated by comparison with suitable model oligomers. The electronic behavior is carefully tuned by creating linear, fulvalene-type and band-type π -conjugation.
