Aryl- and heteroaryl-substituted phenylalanines as AMPA receptor ligands

A series of racemic unnatural amino acids was rationally designed on the basis of recently published X-ray structures of the GluA2 LBD with bound phenylalanine-based antagonists. Twelve new diaryl- or aryl/heteroaryl-substituted phenylalanine derivatives

Photophysical Properties of Silyl-Substituted Stilbene Derivatives

The effects of silyl groups on the structural, absorption, fluorescence, and photoisomerization properties of stilbenes were investigated. In comparison to that of the parent stilbene (1), fluorescence quantum yields (Φf) of Me3Si-substituted stilbenes 2–4 and 6 in solution were higher. Derivative 5, in which Me3Si groups are present at all ortho positions of the arene moieties, did not fluoresce at room temperature. The absorption and fluorescence wavelength maxima of Me3SiMe2Si-substituted stilbene 7 occurred at longer wavelengths compared to those of the Me3Si analog 2. The results of theoretical calculations showed that this difference is a consequence of an increase in the HOMO energy of 7 caused by orbital interaction between π-system and the σ(Si–Si) orbital. Stilbene 14, with two Me3Si-C≡C groups at both para positions, had a high Φf (0.95). The calculated transition dipole moment (μ) was well correlated with Φf. Derivative 21, which contains Ph2N and Me3SiC≡C groups exhibited solvatofluorochromism because it possesses a twisted intramolecular charge transfer (TICT) excited state in which the Ph2N group and the aromatic ring are orthogonal.

Preparation and application of organic thermally induced delayed fluorescence material containing 9,9-dimethyl acridine unit

The invention belongs to the field of organic luminescent materials, and provides preparation and application of an organic thermally induced delayed fluorescence material containing a 9,9-dimethyl acridine unit. Isophthalonitrile with high eletrophilicity is taken as the electron acceptor, a cyano group with a strong electron-withdrawing performance is introduced, 9,9-dimethyl acridine is taken as the electron donor, and a meta-position connection mode is adopted to obtain the organic micromolecular thermally induced delayed fluorescence material with an excellent luminescence property, and the conventional para-position connection mode is broken through. The organic thermally induced delayed fluorescence material, which contains a 9,9-dimethyl acridine unit and adopts a meta-position connection mode, can be applied to vapor deposition of devices. Meanwhile, the organic thermally induced delayed fluorescence material has the advantages of high yield, high thermal stability, and easy film forming, can be massively produced and used in a large scale, and can be applied to electroluminescent devices to obtain a high efficient electroluminescent performance.
