The present paper also reports subtle mirror-symmetry-breaking effects in CD-\/CPL-amplitude and sign, CD\/UV-vis spectral wavelengths, and photodynamics of the aggregates, though the reasons for the anomaly are unsolved. However, these photophysical properties depend on (i) the chemical natures of chiral and achiral molecules when used in solvent quantity,  (ii) clockwise and counterclockwise stirring operations, and (iii) the order of addition of limonene and methanol to the chloroform solution.<\/jats:p>","DOI":"10.3390\/molecules18067035","type":"journal-article","created":{"date-parts":[[2013,6,17]],"date-time":"2013-06-17T11:18:49Z","timestamp":1371467929000},"page":"7035-7057","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":33,"title":["Mirror-Symmetry-Breaking in Poly[(9,9-di-n-octylfluorenyl-2,7-diyl)-alt-biphenyl] (PF8P2) is Susceptible to Terpene Chirality, Achiral Solvents, and Mechanical Stirring"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3139-9478","authenticated-orcid":false,"given":"Michiya","family":"Fujiki","sequence":"first","affiliation":[{"name":"Graduate School of Materials Science, Nara Institute of Science and Technology, 8916-5 Takayama, Ikoma, Nara 630-0192, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshifumi","family":"Kawagoe","sequence":"additional","affiliation":[{"name":"Graduate School of Materials Science, Nara Institute of Science and Technology, 8916-5 Takayama, Ikoma, Nara 630-0192, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoko","family":"Nakano","sequence":"additional","affiliation":[{"name":"Graduate School of Materials Science, Nara Institute of Science and Technology, 8916-5 Takayama, Ikoma, Nara 630-0192, Japan"},{"name":"Department of Materials Science and Engineering, University of California, Berkeley,  CA 94720-1760, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ayako","family":"Nakao","sequence":"additional","affiliation":[{"name":"Graduate School of Materials Science, Nara Institute of Science and Technology, 8916-5 Takayama, Ikoma, Nara 630-0192, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2013,6,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"989","DOI":"10.1039\/CT8977100989","article-title":"Racemism and pseudoracemism","volume":"71","author":"Kipping","year":"1897","journal-title":"J.
