It is interesting to introduce viologen moiety into photoactive compounds such as porphyrin and anthracene in the study of supramolecular system such as pseudorotaxanes. For the construction of photoactive pseudorotaxane based on porphyrin-viologen-anthracene triad or its zinc derivative threaded with bis-p-phenylene-34-crown-10 macrocycle, porphyrin-viologen-anthracene triad 1 and its zinc derivative zinc porphyrin-viologen-anthracene triad 2 were prepared and their absorption and fluorescence spectral properties were measured.

참굴에 다환성방향족탄화수소(PAHs)의 축적성과 이 물질들이 미치는 독성을 평가하기 위해 해양환경에서 빈번히 검출되는 PAHs 중의 하나인 anthracene을 사용한 모델연구를 수행하였다. Anthracene을 0.01-1ppm의 농도로 2주간 참굴에 노출시켰을 때 참굴 조직내의 anthracene의 농도는 노출기간 및 노출강도에 비례하여 최고 25-85배까지 증가하였다. 소화맹낭과 폐각근의 지질 과산화물가는 노출기간 및 노출농도에 관련하여 현저히 증가하였으나 수용성단백질, glycogen, nucleoside/nucleotide 및 핵산의 함량은 변화하지 않았다. 이 결과로 anthracene은 굴의 조직내로 원할하게 축적됨을 확인하였으며 과산화지질의 함량은 anthracene에의 오염에 대한 예민한 생화학적 지표가 될 수 있을 것으로 사료된다.

수용액 중의 fluorene 과 anthracene을 동시화 형광분광법을 이용하여 동시에 정량하는 방법에 대하여 연구하였다. 두 화합물 용액에서의 형광특성을 조사하였고, 화합물 혼합용액을 이용하여 동시화 형광스펙트럼을 측정할 때에 파장차이 (${\Delta}{\lambda}$)가 봉우리의 분리에 미치는 영향을 조사한 결과 ${\Delta}{\lambda}$가 50 nm일 때 가장 좋은 봉우리의 분리가 일어났다. 혼합 수용액으로 최적 ${\Delta}{\lambda}$에서 동시화 형광스펙트럼을 측정하여 검정곡선을 작성하였을 때 fluorene의 경우에는 $5.0{\times}10^{-8}M$에서 $1.0{\times}10^{-3}M$, anthracene의 경우에는 $5.0{\times}10^{-8}M$에서 $1.0{\times}10^{-3}M$까지 직선범위 가 성립하였다. Fluorene과 anthracene의 검출한계는 각각 $3.0{\times}10^{-9}M$과 $7.0{\times}10^{-9}M$이었다.

Luminescence properties of anthracene chromophores were investigated. Anthracene chromophores were incorporated in cyclosiloxane-based hybrid polymers through one-pot hydrosilylation reaction. Using four-armed cyclosiloxanes, divinylterminated siloxane monomers, and 9-vinylanthracenes, anthracene-labeled hybrid polymers were prepared. Free-standing hybrid polymer films were prepared successfully by doctor-blade method and thermal treatment. The polymer films exhibit strong blue fluorescence from anthracene and its fluorescence lifetime was not influenced by the temperature, indicating that the movement of anthracene chromophores was restrained in cyclosiloxane-based hybrid polymer films.

Anthracene derivatives, 9,10trimethylsilylanthr - acene(SA) and bis(2-phenylethynyl)trimethylsilyl anthracene(Si-BPEA) were synthesized and their emission properties were studied with UV and PL spectrometers. The PL maxima of anthracene, SA, bis(2-phenylethynyl)anthracene (BPEA), Si-BPEA were obtained at 401, 438, 475, 478nm, respectively. The electro-optical properties OLED devices made with these anthracene derivatives were discussed.

A series of new organic semiconductors hexyl end-capped thiophene-anthracene oligomers containing the anthracene moiety in the center of the oligomers are synthesized. The target oligomers have been obtained by Stille coupling reactions as key step reactions. The synthesized thiophene-anthracene oligomers were characterized by 1H-NMR, 13C-NMR and high-resolution mass spectroscopy, respectively. All of the oligomers are soluble in chlorinated solvents. Their optical, thermal and electrochemical properties were measured. The hexyl end-capped oligomers and their unsubstituted oligomers exhibit the same absorption behavior in dilute toluene solution. Hexyl end-capped bis-terthienylanthracene oligomer is observed to show liquid crystalline mesophase at 166 oC in heating process. The thermal analyses as well as the electrochemical measurement data indicate that the designed materials show better thermal and oxidation stability than the corresponding oligothiophenes without anthracene core. Fluorescence lifetimes and fluorescence quantum yields of the thiophene-anthracene oligomers are measured to be 10-14 ps and 3.4-9.9 × 10?3 which are much shorter and lower than those of oligothiophenes respectively.

Anthracene is a PAH that is not readily degraded, plus its degradation mechanism is still not clear. Thus, two strains of anthracene-degrading bacteria were isolated from long-term petroleum-polluted soil and identified as Sphingomonas sp. 12A and Pseudomonas sp. 12B by a 16S rRNA sequence analysis. To further enhance the anthracene-degrading ability of the two strains, the biosurfactants produced by Pseudomonas aeruginosa $W_3$ were used, which were characterized as rhamnolipids. It was found that these rhamnolipids dramatically increased the solubility of anthracene, and a reverse-phase HPLC assay showed that the anthracene degradation percentage after 18 days with Pseudomonas sp. 12B was significantly enhanced from 34% to 52%. Interestingly, their effect on the degradation by Sphingomonas sp. 12A was much less, from 35% to 39%. Further study revealed that Sphingomonas sp. 12A also degraded the rhamnolipids, which may have hampered the effect of the rhamnolipids on the anthracene degradation.

Pseudomonas sp. NGK1, isolated by naphthalene enrichment culture technique, is capable of degrading anthracene as a sole source of carbon and energy. The organism degraded anthracene through the intermediate formation of 1,2-dihydroxyanthracene, 2-hydroxy-3-naphthoic acid, salicylate, and catechol. The intermediates were isolated and characterized by TLC, spectrophotometry, and HPLC analysis. The cell free extract of anthracene-grown cells showed activities of anthracene dioxygenase, 2-hydroxy-3-naphthylaldehyde dehydrogenae, 2-hydroxy-3-naphthoate hydroxylase, salicylate hydroxylase and catechol 2,3-dioxygenase. The formed catechol as a metabolite is degraded through meta-cleavage with the formation of ${\alpha}$-hydroxymuconic semi-aldehyde.

유기전기발광 소자에서 천연색을 구현하기 위해서는 적색, 녹색, 청색 발광물질이 필요하다. 그러나 적색과 녹색의 발광 물질에 대한 연구는 매우 활발하나 청색의 물질에 대한 연구가 미흡한 것은 높은 발광 에너지 때문으로 보인다. 본 연구는 발광 효율이 높으며 열적 안정성이 좋은 화합물을 합성하려는 것으로 carbazole로 치환된 anthracene 화합물 합성에 관한 것이다. Tert-butyl 기로 치환된 carbazole에 전기 발광 성질과 열적 안정도가 좋은 anthracene을 직접 결합시킴으로써 정공전달 특성을 갖는 작용기와 전자전달 특성을 갖는 작용기 간의 거리에 대한 연구를 시작하고자 하였다.
