In this paper, by merging the hole-dominated triphenylamine (TPA) and tetraphenylethene (TPE) moieties together with different linkage positions, four derivatives of 1,2-bis[4′-(diphenylamino)biphenyl-4-yl]-1,2- diphenylethene (2TPATPE) were successfully synthesized with confirmed structures, and their thermal, optical and electronic properties were fully investigated. Thanks to the introduction of the meta-linkage mode on the TPE core, their π-conjugation length could be effectively restricted to ensure blue emission. The non-doped OLEDs based on these four emitters exhibit blue emissions from 443-466 nm, largely blue-shifted with respect to the green emission of 2TPATPE (514 nm). Meanwhile, good electroluminescence efficiencies with Lmax, ηC,max, and ηP,max of up to 8160 cd m-2, 3.79 cd A-1, and 2.94 Im W-1 respectively, have also been obtained, further validating our rational design of blue AIE fluorophores.

Page/Page column 19, (2009/04/24)
The present invention relates to semicarbazone or thiosemicarbazone inhibitors of cysteine proteases and methods of using such compounds to prevent and treat protozoan infections such as trypanosomiasis, malaria and leishmaniasis. The compounds also find use in inhibiting cysteine proteases associated with carcinogenesis, including cathepsins B and L.

A series of compounds bearing tetrahydronaphthalene, benzophenone, propiophenone, and related rigid molecular skeletons functionalized with thiosemicarbazone or unsaturated carbonyl moieties were prepared by chemical synthesis and evaluated for their ability to inhibit the enzyme cruzain. As potential treatment agents for Chagas' disease, three compounds from the group demonstrate potent inhibition of cruzain with IC50 values of 17, 24, and 80 nM, respectively.
