摘要: Abstract The fluorescence of pyrene in premicellar solutions Triton X-45 has been measured at a range temperatures. results are compared with those cyclohexane, n -hexane, ethanol, benzene and pure water. Only causes both spectral shift temperature dependent I 1 / 3 ratio change, arising from π-electron interactions. behavior TX-405 suggests that aggregates fairly stable, could possibly nucleate around dissolved pyrene. Excitation energy transfer to associated molecules is also shown occur. donor-acceptor separation 81.5 A.
