Microporous hypercross-linked conjugated quinonoid chromophores represent a novel class of amorphous polymers, synthesized by the reaction of anthracene with dimethoxy methane in the presence of FeCl3 catalyst. Their N2 adsorption isotherms confirm their microporous nature. Diffuse reflectance UV-Visible（DRS UV-Vis） spectroscopy confirms their matrix built with the conjugated quinonoids by their broad light absorption characteristics extending from 1000 nm to 200 nm with the absorbance maximum close to 400 nm. The catalyst cross-linked anthracene with ―CH2― bridges and subsequently dehydrogenating them to form quinonoids. Their Fourier transform infrared（FTIR） spectra showed their characteristic quinonoid vibrations between 1600 and 1700 cm-1. The synthesis of polymers was carried out at 30, 40, 50, 60, 70 and 80 ℃, but the quinonoid content of the polymer obtained at 80 ℃ was higher than that of the others. Their scanning electron microscopy（SEM） images showed microspheres of 1 to 5 μm size built with tiny particles. Their surfaces were not smooth. The polymer synthesized at 80 ℃ showed 5.1 wt% CO2 sorption at 25 ℃ and 0.1 MPa, but when it was recross-linked, the CO2 sorption increased to 8 wt%. Hence, hypercross-linked conjugated quinonoid chromophores of anthracene are good for sorption of CO2.

The present study investigated the efficiency of Aspergillus sydowii strain bpol(GenBank Accession Number:MK373021)in the removal of anthracene(100 mg/L).Optimal degradation efficiency(98.7%)was observed at neutral pH,temperature(30℃),biomass weight(2 g)and salinity(0.2%w/v)within 72 h.The enzyme analyses revealed 131%,107%,and 89%induction in laccase,lignin peroxidase,and manganese peroxidase respectively during anthracene degradation.Furthermore,the degradation efficiency(99.8%)and enzyme induction were significantly enhanced with the addition of 100 mg/L of citric acid and glucose to the culture.At varying anthracene concentrations(100-500 mg/L),the degradation rate constants(K1)peaked with increasing concentration of anthracene while the half-life(t1/2)decreases with increase in anthracene concentration.Goodness of fit(R2=0.976 and 0.982)was observed when the experimental data were subjected to Langmuir and Temkin models respectively which affirmed the monolayer and heterogeneous nature exhibited by A.sydwoii cells during degradation.Four distinct metabolites;anthracene-1,8,9(2H,8aH,9aH)-trione,2,4adihydronaphthalene-1,5-dione,l,3,3a,7a-tetrahydro-2-benzofuran-4,7-dione and 2-hydroxybenzoic acid was obtained through Gas Chromatography-Mass spectrometry(GC-MS).A.sydowii exhibited promising potentials in the removal of PAHs.

Two kinds of novel blue-emitting materials, anthracene-based derivatives, are synthesized by the Suzuki cou- pling reaction. It is worth noting that the maximum emission wavelengths of the two materials are 441 and 444 nm in tetrahydrofuran and 456 and 454 nm in film states, which are the typical blue fluorescence and the fluorescence quantum yields of them are 0.87 and 1.12 by using 9,10-diphenylanthracene （Фf = 0.90） as a calibration standard. The full width at half maximum of them are 56, 55 nm in solution, respectively, pre- senting good color purity. Both of them display superior thermal properties and electrochemical properties. Scanning electronic microscope results show that the films of two compounds are continuous, compact, and smooth after 100℃ for 3 h. These data indicate their potential to be prepared for high efficiency and long operation lifetime organic light-emitting diodes devices.

An asymmetric anthracene derivative(4-HDPA) was designed and synthesized. With the optimization of proper scenario of fabrication process, top-contact thin film devices based on 4-HDPA exhibit mobility as high as 3.59 cm^2 V^(–1) s^(–1), while its singlecrystal devices exhibit mobility as high as 5.12 cm^2 V^(–1) s^(–1), which is higher than the symmetrical counterpart of 4-HDPA in both single-crystal and thin film devices.

Ultrasonic-assisted extraction(UAE)combined with medium pressure liquid chromatography(MPLC)was designed for carbazole separation from anthracene slag(AS).The effects of liquid/solid ratio,temperature,and extraction times on carbazole separation were investigated.When using CC14 and ethyl acetate as extraction solvents and combining with MPLC,carbazole recovery and purity are 75.1%and 95.4%,respectively.The mechanism for carbazole separation were presumed by examining intermolecular interactions such as N-H…π,π-π,and C-Cl…πinteractions.These results demonstrate that UAE/MPLC has a considerable potential as a green and promising strategy for separating and purifying carbazole and other chemicals from AS.

Two novel anthracene derivatives containing 4-vinylpyridine （FPEA） and 2-vinylpyridine （TPEA） poly（methyl methacrylate） films are prepared on quartz glass substrates. Their nonlinear absorption properties are investigated by using a 120-fs, 800-nm Ti：sapphire femtosecond pulsed laser operating at a 1-kHz repetition rate. The unique nonlinear absorption properties of these new compounds are observed by utilizing a Z-scan system. These two-photon absorption （TPA） properties are proven by the two-photon fluorescence excited at 800 nm. The FPEA and TPEA films have nonlinear TPA coefficients of 0.164 and 0.148 cm/GW and the TPA cross sections of 3.345 × 10^-48 and 3.081 × 10^-48 cm4 ·s/photon, respectively. The influence of the chemical structures on the nonlinear TPA properties of the compounds is also discussed. The highly nonlinear TPA activities of the films implied that the new anthracene derivatives are suitable materials with promising applications in super-high-density three-dimensional data storage and nano- or microstructure fabrication.

The basic characteristics of anthracene（AN） and dibenz[a,c]anthracene（D[a,c]A） derivatives, important semiconductors, were systematically studied. Differential scanning calorimetry（DSC） shows that D[a,c]A has the reversibility of solid and liquid phases. Thermalgravimetric analysis（TGA） shows that D[a,c]A exhibits higher Td（decomposition temperature）, which indicates D[a,c]A, as active layers, should be more suitable to being made into stable devices. D[a,c]A shows blue-shifted UV-Vis absorption and emission despite increased conjugation compared to anthracene due to different symmetries. Both the compounds are planar and show weak blue fluorescence in the tetrahydrofuran（THF） solution and higher fluorescence in the solid-state, due to different energy levels in solution and solid-state, explained via Jablonski diagram.

A series of tetracene-doped anthracene crystals with different doping concentrations(the highest mo-lar ratio 100:1) are grown from solution.Crystal structures and optical characteristics of the above mixed crystals are investigated at room temperature.By changing the doping concentrations,the fluorescence can be adjusted from blue-green to green and even to yellow-green.The emission spectra of anthracene/tetracene(An/Te) mixed crystals reveal the sensitized fluorescence of tetracene and the partial quenching of anthracene emission.The data of transient photoluminescence(PL) decays illus-trate that in An/Te mixed crystals,the decay of anthracene becomes faster,while the PL lifetime of tet-racene is longer than that of the tetracene single crystals.All above experimental results suggest that there is excitation energy transfer from anthracene to tetracene in the mixed crystals.

Photoinduced electron-transfer system of anthracene-N, N-diethylaniline (MA) was studied in the oil in water (O/W) microemulsions formed by SDS (sodium dodecyl sulfate), BA (benzyl alcohol) and H2O. The time-resolved fluorescence study showed mat the fluorescence quenching of the excited anthracene by DEA occurs at the interface of the O/W microemulsions. Besides as the quencher of the excited anthracene, N, N-diethylaniline could act as a cosurfactant to change the structures of the microemulsions, Just as BA did. The quenching rate constants for the different structures of the system were determined.
