Computed Properties of C13H8O2. Recently I am researching about ELECTRON-TRANSFER; HYDRIDE; IONS; DYES; AGGREGATION; REDUCTION; ROSAMINE; PROTON, Saw an article supported by the Research Corporation for Science Advancement Cottrell College Science AwardResearch Corporation for Science Advancement [22480]; American Chemical Society Petroleum Research Fund (ACS PRF)American Chemical Society [51259-UNI1]; Student Blugold Commitment Differential Tuition (BCDT) funds through the University of WisconsinEau Claire Faculty/Student Research Collaboration Grants program; Wisconsin Louis Stokes Alliance for Minority Participation (WiscAMP). Published in PERGAMON-ELSEVIER SCIENCE LTD in OXFORD ,Authors: Meyer, SM; Charlesworth-Seiler, EM; Patrow, JG; Kitzrow, JP; Gerlach, DL; Reinheimer, EW; Dahl, BJ. The CAS is 2005-10-9. Through research, I have a further understanding and discovery of 6H-Benzo[c]chromen-6-one
This report describes the synthesis of five new colorful 6-aryldibenzo[b,d]pyrylium cation salts, a largely unexplored structural unit. These rare compounds are benzannulated structural derivatives of the well-known flavylium cations found widespread in natural pigments. These new dyes are directly compared to three previously synthesized 6-aryldibenzo[b,d]pyrylium cation salts as well as eight colorful isomeric 9-aryldibenzo[b,d]pyrylium cation, or 9-arylxanthylium, salts. The 9-arylxanthylium unit is commonly found in the biologically important rhodamine and rosamine dyes, yet six of the analogs presented in this study were either previously unreported or not isolated. The visual and spectroscopic properties of all 16 compounds were analyzed as a function of the structural differences between the compounds. All compounds displayed reversible halochromism in organic solution, displaying bright colors under acidic conditions and becoming colorless under basic conditions. (C) 2020 Elsevier Ltd.
