资源简介：
Zn(II) complexes of the following new, fluorine-containing,
benzothiazole-derived ligands have been synthesized and characterized
crystallographically: 2-(3,3,3-trifluoro-2-oxopropyl)benzothiazole
(3), 4,5,6,7-tetrafluoro-2-(3,3,3-trifluoro-2-oxopropyl)benzothiazole
(4), 4,5,6,7-tetrafluoro-2-(2-hydroxyphenyl)benzothiazole
(12), 2-(3,4,5,6-tetrafluoro-2-hydroxyphenyl)-4,5,6,7-tetrafluorobenzothiazole
(13), and 2-(3,4,5,6-tetrafluoro-2-hydroxyphenyl)benzothiazole
(16); the Cu(II) complex of ligand 4 is
also reported. These are analogs of the important photo- and electroluminescent
material [Zn(BTZ)2]2, where H-BTZ = 2-(2-hydroxyphenyl)benzothiazole.
DFT calculations indicate that HOMO and LUMO energy levels in these
materials are substantially lowered by fluorination. The fluorinated
ZnL2 complexes are mononuclear (in contrast to the dinuclear,
nonfluorinated material [Zn(BTZ)2]2). They easily
sublime and show broad visible photoluminescence. A common crystallographic
feature is the existence of pairs of fluorinated ZnL2 molecules
related by inversion centers, with their π systems facing one
another.
