To realize liquid transportation in these TMAs, LCPs should have excellent photodeformation property and suitable mechanical properties. Herein, linear liquid crystal polymers (LLCPs) with different mesogen orientations are used to prepare TMAs to study their liquid transportation behaviors. The mesogen orientation in each LLCP is formed spontaneously and varies with the spacer length, leading to different deformations of LLCP films. It is found that only LLCPs with mesogens oriented out\u2010of\u2010plane realize self\u2010support of the TMAs, whereas the TMAs with mesogens oriented in\u2010plane are so weak that they collapse in the radial direction, indicating the importance of mesogen orientation in fabricating three\u2010dimensional structures. Upon attenuated 470\u2009nm light irradiation, the TMAs deform to an asymmetric conical structure, leading to the motion of liquid slug toward the narrow side. The liquid motion is accelerated in the TMA with longer spacer, showing the control of liquid speed by the mesogen orientation. These photocontrolled TMAs are expected to be applied in biological applications, such as whole blood analysis and flow cytometry, for precise liquid manipulation.<\/jats:p><\/jats:sec>","DOI":"10.1002\/aisy.201900060","type":"journal-article","created":{"date-parts":[[2019,8,15]],"date-time":"2019-08-15T08:50:16Z","timestamp":1565859016000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":32,"title":["Photocontrolled Liquid Transportation in Microtubes by Manipulating Mesogen Orientations in Liquid Crystal Polymers"],"prefix":"10.1002","volume":"1","author":[{"given":"Quan","family":"Liu","sequence":"first","affiliation":[{"name":"Department of Materials Science State Key Laboratory of Molecular Engineering of Polymers Fudan University  220 Handan Road Shanghai 200433 China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuyun","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Materials Science State Key Laboratory of Molecular Engineering of Polymers Fudan University  220 Handan Road Shanghai 200433 China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiu-an","family":"Lv","sequence":"additional","affiliation":[{"name":"Department of Materials Science State Key Laboratory of Molecular Engineering of Polymers Fudan University  220 Handan Road Shanghai 200433 China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erqiang","family":"Chen","sequence":"additional","affiliation":[{"name":"Beijing National Laboratory for Molecular Sciences Key Laboratory of Polymer Chemistry and Physics of Ministry of Education Peking University  Beijing 100871 China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4623-3331","authenticated-orcid":false,"given":"Yanlei","family":"Yu","sequence":"additional","affiliation":[{"name":"Department of Materials Science State Key Laboratory of Molecular Engineering of Polymers Fudan University  220 Handan Road Shanghai 200433 China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2019,8,15]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.progpolymsci.2008.07.001"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1039\/C6TB02576E"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.biomaterials.2007.01.030"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1039\/c3sm51517f"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1039\/C8TA04725A"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature05058"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1039\/C6TB02712A"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1039\/C4TB01604A"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1360\/972010-1955"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1039\/C6TB02372J"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1039\/C6TC00718J"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1039\/C7LC00954B"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1039\/c2lc40596b"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature19344"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.30.139"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1063\/1.3039070"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1039\/c001324b"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.200904868"},{"key":"e_1_2_7_20_1","doi-asserted-by":"publisher","DOI":"10.1038\/nmat1455"},{"key":"e_1_2_7_21_1","doi-asserted-by":"publisher","DOI":"10.1021\/la5001254"},{"key":"e_1_2_7_22_1","first-page":"1679","volume":"11","author":"Qing X.","year":"2017","journal-title":"Acta Polym.
