Synthesis of 1,6-disubstituted pyrene-based conjugated microporous polymers for reversible adsorption and fluorescence sensing of iodine

Here we present detailed evidence of highly efficient iodine capture and sensing in 1,6-disubstituted pyrene-based fluorescent conjugated microporous polymers, which were synthesized by a Sonogashira-Hagihara polycondensation reaction (TDP), trimerization

Synthesis, structural and spectral properties of diarylamino-functionalized pyrene derivatives via Buchwald-Hartwig amination reaction

A new series of diarylamino-functionalized pyrene derivatives, namely, 1-(N,N-diarylamino)-substituted pyrenes (7), isomer of 1,6-bis- and 1,8-bis(N,N-diarylamino)-substituted pyrenes (8/9) and 1,3,6,8-tetrakis(N,N- diarylamino)-substituted pyrenes (10) have been synthesized. The structures of these synthesized compounds were determined on the basis of spectral data and elemental analysis. All compounds 7-10 have bright fluorescent emissions from sky-blue to green in solution condition (λmax = 464-500 nm in CH2Cl2) and high emission efficiency (Φf = 0.84-0.96 in dichloromethane). All compounds have high thermal stability and good solubility in common organic solvents. The electronic properties of these compounds were determined by spectroscopic methods such as UV-vis absorption spectroscopy and fluorescence emission spectroscopy. Clear evidences were obtained that the longest wavelength bands of these compounds are bathochromically red-shifted as the number of the diarylamino-substituent increased.

Asymmetrical Aryl Amine Derivative for Organic Electroluminescence Devices, Method for Preparing Same, Organic Thin Film for Organic Electroluminescence Devices and Organic Electroluminescence Device Using Same

Provided are asymmetric arylamine derivatives for an organic electroluminescent element, represented by the formula (1), which is prepared by sequentially inducing a secondary amine and a tertiary amine to an aryl compound Ar core so that they do not include a symmetrical axis and a symmetrical surface in a molecule, a manufacturing method of the same, an organic thin layer material including the asymmetric arylamine derivatives, and an organic electroluminescent element employing the same: wherein Ar represents a C10-C20 divalent aryl group, Ar1 is a divalent C6-C30 aryl group, and Ar2 to Ar5 each independently represents a divalent C6-C30 aryl group, at least one of Ar2 to Ar5 having a different structure when the secondary amine and the tertiary amine in Ar are substituted at symmetrical positions, and Ar2 to Ar5 having the same structure or different structures when the secondary amine and the tertiary amine in Ar are substituted at asymmetrical positions. The asymmetric arylamine derivative can be used in forming an organic thin layer for an organic electroluminescent element. When the organic electroluminescent element is formed using a dopant as an emitting material, the asymmetric arylamine derivative exhibits superb emission efficiency and an excellent lifetime characteristic in a blue wavelength region.

Emission color tuning and deep blue dopant materials based on 1,6-bis(N-phenyl-p-(R)-phenylamino)pyrene

(Graph Presented) Panchromatic 1,6-bis(N-phenyl-p-(R)-phenylamino)pyrenes, 2R, were obtained from Buchwald-Hartwig coupling reactions between N-phenyl-p-(R)-phenylamines and 1,6-dibromopyrene. The photophysical properties of 2R corresponded well to the electron-withdrawing and -donating nature of the diarylamine substituents, exhibiting a full color visible range between 454 and 620 nm. In particular, a deep blue 2CN showed a high radiative rate constant of 2.85 × 108 s-1 with high emission quantum efficiency of 79%. Further applications of 2CN as a blue dopant were attempted using multilayer organic light-emitting devices. A maximum efficiency of 3.98 cd/A with CIE coordinates of x = 0.14, y = 0.10 were obtained. 2009 American Chemical Society.
