Abstract
The photophysical properties of 1,4-bis(4'-pyridylethynyl)-2,5-di(n-hexylox y)benzene and 1,4-bis(4'-pyridylethynyl)benzene in both solution as well as in solid films were investigated Both compounds exhibit concentration-depe ndent fluorescence in solution. The fluorescent bands red shift in solution at high concentration and in solid films and the emission is ascribed to t he formation of excimers. (C) 2001 Elsevier Science B.V. All rights reserve d.
