Organic electroluminescence material containing phenanthrene structure and organic luminescence device thereof

The invention provides an organic electroluminescence material containing a phenanthrene structure and an organic luminescence device thereof, and belongs to the technical field of organic photoelectric materials. The structure of the organic electroluminescence material containing the phenanthrene structure contains the phenanthrene ring structure, wherein the phenanthrene ring structure is a blue ray structure which is excellent in performance and has a higher triplet state energy level and a wider energy gap, and in molecules, through connection with benzimidazole groups, the electron transportation capability of the blue ray main structure is enhanced, so that carrier transportation is balanced. Compared with the prior art, the material has the advantages that the material is applied to the organic luminescence device and especially used as the blue luminescence material in a luminescence layer, the luminescence efficiency is relatively high, and the driving voltage is relatively low.

Effect of the planar center moiety for a donor-acceptor polymeric electrochrome

In this work, phenanthrene centered donor-acceptor monomer; 5,10-bis(4-hexyl-2-thienyl)phenantro[9,10-c][1,2,5]thiodiazole; MES16 was synthesized and then its electrochromic application of corresponding polymer was carried out. 4,7-di(thiophen-2-yl)-2,1,3-benzothiadiazole (TST) was also synthesized as a standard molecule to determine the effect of the planar phenanthrene center on electrochromic performance. Electrochemical properties were elucidated by cyclic voltammetry and then HOMO-LUMO band gaps were calculated by using their oxidation and reduction onset potentials. Finally, electrochromic properties of poly-(MES16) and poly-(TST) were investigated via spectro-electrochemical measurements. DFT calculations exhibit that poly-(MES16) has a high planarity and an intramolecular charge transfer from the polymer backbone-donor to thiadiazole-acceptor subunit. Because of high solid state π?π interactions of the poly-(MES16), a good quality film was obtained corresponding to self-assembly property planar phenantrene center. Owing to this property, electrochromic performance of poly-(MES16) such as response time, stability and ΔT% were better than the standard poly-(TST).

Electrochromic properties of phenantrene centered EDOT polymers

A series of phenantrene centered donor-acceptor type electroactive 3,4-ethlenedioxythiophene (EDOT) monomers (EP-X) containing N, S and Se heteroatom on the bezophenantra-X-diazole acceptor unit have been synthesized by Stille coupling reaction. These monomers were electrochemically polymerized by potentiodynamic method to obtain electrochromic polymer films. Spectro-electrochemical properties were also investigated by UV-vis absorption connected with the cyclic voltammetry measurements. The polymer films exhibited a remarkable trend of visible color (yellow, orange, red) at the neutral state due to changing the central acceptor moiety. These polymer films have multielectrochromic properties by means of moderately changing the absorbance/transmittance at the visible regime upon applied positive potentials. The donor-acceptor interaction at the neutral state correlated by DFT calculations was also supported by the interesting trend in the colors of these polymers. Finally, the electrochromic performance of EP-X polymer films represented a high redox stability, reasonable contrast ratio, coloration efficiency and response times.
