Fluorescent Coordination Networks of 2,3,6,7,10,11-Hexakis(phenylthio)triphenylene and Silver(I) Triflate

The polycyclic aromatic ligand 2,3,6,7,10,11-hexakis(phenylthio)triphenylene (HPhTT) coordinates with AgTf (Tf =
trifluoromethylsulfonate) to form 1D networks with various solvent molecules included. In particular, the crystal
structures and photoluminescent properties of compound 1 (formula = 2HPhTT·3AgTf·3toluene) and compound 2
(formula = 2HPhTT·3AgTf·2THF) are described. Both 1 and 2 feature similar network connectivity as well as
similar local coordination environments around the silver(I) atoms. The organizations of the guest molecules in the
two structures are, however, quite different:  In 1, the toluene molecules are enclathrated in isolated cavities by the
host network; in 2, the THF molecules are confined in continuous 1D channels. Because of the large aromatic
system of the triphenylene moiety, strong fluorescent bands (room temperature) are observed for HPhTT, 1 and
2, with λF,max = 447 nm for HPhTT and λF,max = 440 nm for both 1 and 2.
