Fluorene 발색단의 PL특성
Photoluminescence of donor-acceptor fluorene chromophore
초록
1-(9,9-Di-octyl-fluorenyl)-2-substituted-2-cyanvinylene was synthesized and emission feature in solution are presented. Photoluminescence characteristics of 1-(9,9-Di-octyl-fluorenyJ)-2-substituted-2-cyanvinylene are measured by solvents such as carbon tetrachloride, normal hexane, chloroform, ethylaccetate, acetonitrile, methanol. It is shown that depending in the strength of the donor-acceptor internal charge transfer, and emission spectra are more or less red-shifted.
