The PPQ\u2010<jats:italic>b<\/jats:italic>\u2010PS aggregated domain sizes in the ES fibers prepared from dichloromethane (CH<jats:sub>2<\/jats:sub>Cl<jats:sub>2<\/jats:sub>), chlorobenzene (CB) and chloroform (CHCl<jats:sub>3<\/jats:sub>) were 1.5\u2009\u00b1\u20090.5, 2.2\u2009\u00b1\u20090.4 and 4.1\u2009\u00b1\u20091.1\u2009\u00b5m, respectively. Such variation on the aggregation size led to the red\u2010shifting photoluminescence spectra changing from green, to yellow, and orange. ES fibers prepared from CH<jats:sub>2<\/jats:sub>Cl<jats:sub>2<\/jats:sub> exhibited pH\u2010tunable photoluminescence and the emission maximum varied from 532 to 560\u2009nm as the pH value changed from 7 to 1. The study demonstrated that the ES fibers prepared could have potential applications for sensory devices.<\/jats:p><jats:p><jats:boxed-text content-type=\"graphic\" position=\"anchor\"><jats:graphic xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" mimetype=\"image\/jpeg\" position=\"anchor\" specific-use=\"enlarged-web-image\" xlink:href=\"graphic\/mgra001.jpg\"><jats:alt-text>magnified image<\/jats:alt-text><\/jats:graphic><\/jats:boxed-text>\n<\/jats:p>","DOI":"10.1002\/marc.200900566","type":"journal-article","created":{"date-parts":[[2009,11,18]],"date-time":"2009-11-18T21:34:10Z","timestamp":1258580050000},"page":"65-70","source":"Crossref","is-referenced-by-count":44,"title":["Morphology and pH Sensing Characteristics of New Luminescent Electrospun Fibers Prepared from Poly(phenylquinoline)\u2010<i>block<\/i>\u2010Polystyrene\/Polystyrene Blends"],"prefix":"10.1002","volume":"31","author":[{"given":"Chi\u2010Ching","family":"Kuo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi\u2010Chih","family":"Tung","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wen\u2010Chang","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2009,12,23]]},"reference":[{"key":"e_1_2_6_1_2","unstructured":"\u00a0"},{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1088\/0957-4484\/7\/3\/009"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/adma.200400719"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/marc.200800381"},{"key":"e_1_2_6_5_2","unstructured":"\u00a0"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja030326i"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1021\/ma047529r"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1002\/marc.200600769"},{"key":"e_1_2_6_9_2","unstructured":"\u00a0"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1021\/ma071182l"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1002\/mame.200800224"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1002\/marc.200800491"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1002\/polb.21651"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1002\/macp.200900097"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.1088\/0957-4484\/20\/37\/375604"},{"key":"e_1_2_6_16_2","unstructured":"\u00a0"},{"key":"e_1_2_6_17_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.279.5358.1903"},{"key":"e_1_2_6_18_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.283.5400.372"},{"key":"e_1_2_6_19_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.265.5173.765"},{"key":"e_1_2_6_20_2","unstructured":"\u00a0"},{"key":"e_1_2_6_21_2","doi-asserted-by":"publisher","DOI":"10.1021\/nl020216u"},{"key":"e_1_2_6_22_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja067856"},{"key":"e_1_2_6_23_2","doi-asserted-by":"publisher","DOI":"10.1002\/masy.200950506"},{"key":"e_1_2_6_24_2","doi-asserted-by":"publisher","DOI":"10.1002\/marc.200700134"},{"key":"e_1_2_6_25_2","unstructured":"\u00a0"},{"key":"e_1_2_6_26_2","doi-asserted-by":"publisher","DOI":"10.1021\/ma010086w"},{"key":"e_1_2_6_27_2","doi-asserted-by":"publisher","DOI":"10.1002\/adma.200601530"},{"key":"e_1_2_6_28_2","doi-asserted-by":"publisher","DOI":"10.1021\/ma50004a006"},{"key":"e_1_2_6_29_2","doi-asserted-by":"publisher","DOI":"10.1021\/cm061719u"},{"key":"e_1_2_6_30_2","doi-asserted-by":"publisher","DOI":"10.1021\/ma020444a"},{"key":"e_1_2_6_31_2","volume-title":"Properties of Polymers: Their Correlation with Chemical Structure; Their Numerical Estimation and Prediction from Additive Group Contributions","author":"Van Krevelen D.
