Synthesis, optical, and electrochemical properties of 2,3-diphenyl-10H- indeno[1,2-g]quinoxaline, 15H-dibenzo[a,c]indeno[1,2-i]phenazine, and 15H-indeno[1,2-i]phenanthro[4,5-abc]phenazine derivatives

A series of 2,3-diphenyl-10H-indeno[1,2-g]quinoxaline, 15H-dibenzo[a,c] indeno[1,2-i]phenazine, and 15H-indeno[1,2-i]phenanthro[4,5-abc]phenazine derivatives containing different terminal aromatic units such as phenyl, phenylethynyl, naphthyl, anthryl, pyrenyl, or 4-(diphenylamino)phenyl have been synthesized by employing palladium-catalyzed C-C cross-coupling reactions in good yields. All of the target compounds were characterized using 1H NMR, 13C NMR, high resolution MS, optical absorption, and emission spectra. Even though the electronic absorption spectra of the compounds were influenced by the nature of the peripheral arenes, the emission spectra indicated close similarity for the excited states in the 15H-indeno[1,2-i] phenanthro[4,5-abc]phenazine series compounds. Most compounds possess a medium fluorescence-emitting ability with φFL values in the region of 0.40-0.71 and displayed blue, green, yellow, or red emission depending on the nature of the whole molecule. Structure-optical behavior characteristics and further details of the electronic properties from cyclic voltammetry measurements and theoretical calculations were discussed.

White-light emitting hydrogen-bonded supramolecular copolymers based on #-conjugated oligomers

Three different ?-conjugated oligomers (a blue-emitting oligofluorene, a green-emitting oligo(phenylene vinylene), and a red-emitting perylene bisimide) have been functionalized with self-complementary quadruple hydrogen bonding ureidopyrimidinone (UPy) units at both ends. The molecules self-assemble in solution and in the bulk, forming supramolecular polymers. When mixed together in solution, random noncovalent copolymers are formed that contain all three types of chromophores, resulting in energy transfer upon excitation of the oligofluorene energy donor. At a certain mixing ratio, a white emissive supramolecular polymer can be created in solution. In contrast to their unfunctionalized counterparts, bis-UPy-chromophores can easily be deposited as smooth thin films on surfaces by spin coating. No phase separation is observed in these films, and energy transfer is much more efficient than in solution, giving rise to white fluorescence at much lower ratios of energy acceptor to donor. Light emitting diodes based on these supramolecular polymers have been prepared from all three types of pure materials, yielding blue, green, and red devices, respectively. At appropriate mixing ratios of these three compounds, white electroluminescence is observed. This approach yields a toolbox of molecules that can be easily used to construct ?-conjugated supramolecular polymers with a variety of compositions, high solution viscosities, and tuneable emission colors.

Synthesis and biological activities of aryl-ether-, biaryl-, and fluorene-aspartic acid and diaminopropionic acid analogs as potent inhibitors of the high-affinity glutamate transporter EAAT-2

Excitatory amino acid transporters (EAATs) play a pivotal role in maintaining glutamate homeostasis in the mammalian central nervous system, with the EAAT-2 subtype thought to be responsible for the bulk of the glutamate uptake in forebrain regions. A complete elucidation of the functional role of EAAT-2 has been hampered by the lack of potent and selective pharmacological tools. In this study, we describe the synthesis and biological activities of novel aryl-ether, biaryl-, and fluorene-aspartic acid and diaminopropionic acid analogs as potent inhibitors of EAAT-2. Compound (16) represents one of the most potent (IC50 = 85 ± 5 nM) and selective inhibitors of EAAT-2 identified to date.

Synthesis of Alkylated Aminofluorenes by Palladium-Catalyzed Substitution at Halofluorenes

New N-substituted 2-amino-9,9-dialkylfluorenes optionally bearing electron-withdrawing substituents such as nitro or cyano in position 7 can be synthesized starting from 2-halo-9,9-dialkylfluorenes by Pd-catalyzed substitution with amines. Chiral amino groups can be introduced by this method too. 2-N,N-Dimethylamino-7-nitro-9H-fluorene was obtained in a convenient way by reductive amination. The N-substituted 2-amino-7-nitro-9H-fluorenes are promising candidates for fluorescence probes for femtosecond solvation dynamics.
