We created chiral LC fields with thermally or optically controlled helicity. We dynamically controlled helical sense of helical polyacetylene and helical polyethylenedioxythiophene (PEDOT) that were synthesized through chemical and electrochemical polymerizations in the chiral LC fields, respectively. We achieved the control of helicity and circularly polarized luminescence of helical conjugated polymers using external forces.

我们创造了具有热或光学控制螺旋度的手性LC场。对通过化学聚合和电化学聚合合成的螺旋聚乙炔和螺旋聚二氧噻吩（PEDOT）在手性LC场中的螺旋感进行了动态控制。利用外力控制螺旋共轭聚合物的螺旋度和圆极化发光。
