英文摘要	Chiral columns formed by a helical cis-polyphenylacetylene (PPA) derivative P1 are reversibly switched during a phase transition between two chiral columnar phases: the frustrated phi(3D-SL)(h) phase containing four chains at low temperature and a hexagonal columnar phase phi(h) at high temperature, accompanied by a simultaneous conformational change. The helix-helix transition along the PPA backbone during the phi(3D-SL)(h)-phi(h) transition makes the uniaxially oriented P1 capable of reversibly and reproducibly elongating (132%) upon heating and contracting upon cooling, exhibiting the behavior of a two-way shape actuator.; National Natural Science Foundation of China [51273002, 21374086, 21304069, 20990232]; SCI(E); EI; PubMed; ARTICLE; feng.liu@xjtu.edu.cn; eqchen@pku.edu.cn; 17; 2387-2391; 11
