새로운 반응성염료 개발의 일환으로 trifluoro-s-triazine을 반응성분으로 이용하여 한 분자에 2개의 서로 다른 chromophore를 가지는 반응성염료를 합성한 다음, 이의 가수분해속도와 면섬유에 대한 염색성을 조사하였다. 이 염료의 유사 일차 가수분해속도상수, $k_w$는 pH=10.0, 온도 $60{\circ}C$에서 k_w=2.6{\times}10^{-2}min^{-1}$로서 monochlorotriazine 반응성염료보다 높은 값을 보였으며 염착률과 고착율 역시 monochlorotriazine 계 염료보다 우수하였다. 얻어진 반응성 염료는 황색계열로서 수율은 75%였다. Triazinyl reactive dye containing two different chromophore was synthesized by using trifluoro-s-triazine as reactive component. The yield of this dye was 72% and its colour was yellowish red as a mixed shade. The hydrolysis rate and dyeing properties of this dye were studied and compared with monochlorotriazinyl reactive dye. It was found that monofluorotriazinyl reactive dye showed much higher hydrolysis rate than monochlorotriazinyl reactive dye.

Selective complexation of anions is more demanding than that of cations due to the many reasons such as size, charge density, polarizability, solvation energy and pH-dependent acid-base equilibria.1,2 Anion plays a fundamental role in a wide range of chemical and biological processes, and numerous efforts have been devoted to the development of abiotic receptors for anion species,3 but they are still very limited. Urea derivatives have been utilized successfully as neutral host compounds for the various anion guests through hydrogen bonding.4-7 Recently for the development of cation calixtube, a number of dimeric structure of calix[4]arene biscrown were synthesized and their cation binding properties were investigated.8,9 But, the calix[4]arene dimer structure of bridged urea anion receptors have not reported yet except our previous work which describe the bridged dimeric urea derivative of calix[4]arene as a minor side product.10 For the purpose of developing the calixtube of anion receptors, we synthesized the urea bridged dimer of calix[4]arene 3 from the bridging reaction of diisocyanate calix[4]arene 2 and its aminocalix[4]arene precursor 1. Also the oxidized quinone derivative 4 was obtained by the oxidation of 3 with TTFA (thallium trifluoroacetate). X-ray structure and anion binding properties were investigated.

Calix[6]arene을 포름알데히드와 이차아민과 반응시키면 물에 녹는 칼릭세린 염기가 얻어진다. 이를 메틸요오드로 처리하여 암모늄 염을 만들고 다양한 친핵성 물질과 반응시키면 칼릭세린의 파라위치에 작용기가 포함된 calix[6]arene이 얻어진다. Calix[6]arene도 포름알데히드와 이차의 아릴아민과 반응시켜 물에 녹는 칼릭세린 아민을 만들었다. 이렇게 합성된 칼릭세린중 물에 녹는 아민과 산기가 포함된 calix[6]arene과 calix[8]arene을 운반체로 이용하여 중성의 방향족 물질들을 통과시키는 연구를 U 형태의 유리관을 이용하여 수행하였다. 방향족 기질들로는 나프탈렌, 안트라센, 파이렌, 풀우란텐 등의 고체물질을 사용하였다. Calix[6]arene react with formaldehyde and secondary amines to yields water soluble Mannich bases which can be converted to the corresponding quaternary salts. Treatment of the quaternary salts with a nucleophile such as cyano, ethoxy, and hydride yields p-substituted calix[6]arenes. Calix[8]arene too react with formaldehyde and diallyl amine to yield a water soluble Mannich base. The transport of neutral arenes through an aqueous phase along a concentration gradient mediated by those of water soluble calixarenes as molecular carrier was studied in a U-type cell. Naphthalene, anthracene, pyrene, and fluoranthene are tested as a neutral solid guest compounds for the transport experiment.

Synthesis and Metal Binding Properties of Anthraquinone Bridged with Coumarin
류병주,조은진,남계춘 대한화학회 2007 Bulletin of the Korean Chemical Society Vol.28 No.9
Molecular switching in macrocyclic polyether systems has been the subject of intense study during the past 30 years. Especially, photochemical switching has been well-studied by Shinkai, Ueno, Takagi, Tabushi, and others.1 In addition, changes in pH,2 light3 and oxidation-reduction chemistry4 have all been explored as switching mechanisms. The lariat ethers,5 podands having nitroaromatic sidearms6 and similar species derived from anthraquinones have been concerned with electrochemical switching. Especially the anthraquinone system is an interesting one for the study of reducible and switchable lariat ethers7 because its anion is stable for months in water so long as oxygen is excluded.8 Although podands (noncyclic polyethylene glycols) generally exhibit poor cation binding, when combined with the semiquinone nucleus, very strong cation complexation is observed for the radical anion.3,9 The anthraquinone podands can be used for electrochemically switched cation transport in bulk organic membranes7b and both monoanion and dianion species can be formed and detected.10 Both one-electron and two-electron reduction can lead to enhanced cation binding in anthraquinone-derived podands and lariat ethers.7a Anthraquinones differ significantly from the nitroaromatic systems in their ability to undergo discrete one or two electron reduction and also anthraquinone substituted podands exhibit surprising geometrical effects during the electrochemical switching process.7b Gokel and co-workers10 have reported two armed podands based on the anthraquinone ring systems, which showed the cation binding enhancement by cyclic voltammetry. 1,8-Anthraquinone derived crown ether having a total of six oxygen donors in the macrocycling is an exceptionally strong cation binder not only when reduced, but in its neutral form as well. Anthraquinone plays an important role in the various photochemical and colorimetric sensor systems. In addition, coumarins11 are interesting chromophores by their photochemical and photophysical properties, and have been used to convert crown ethers into fluorescent probes for alkali metal ions. Herein we synthesized a new cation receptor 4 which combined coumarin and anthraquinone with ether units, and studied the binding properties of cation guests
