Temperature-dependent helix-helix transition of an optically active poly (diarylsilylene)
Temperature-dependent helix-helix transition of an optically active poly (diarylsilylene)
The poly(diarylsilylene) copolymer mainchain helix in (Ar*2Si)x(Ar2S i)1?x [Ar* = 3-(S)-2-methylbutylphenyl, Ar = 4-butylphenyl, x = 0.2] undergoes a thermally driven inversion of helical screw sense with a transition temperature of -10℃
