  A competition between normal substitution and tele-substitution is observed with 9-bromoanthracenes bearing in the opposite meso position an ethyl, 1b, or a benzyl group 1d. When treated with potassium phenoxide in HMPT these bromides afford mixtures of 9-alkyl-10-phenoxy-anthracenes 2 and 9-(α(phenoxyalkyl) anthracenes 3. On the other hand 9-bromo-10 isopropylanthracene 1c is quite unreactive and

  观察到正常取代和遥取代之间的竞争，其中9-溴蒽在相反的内消旋位置带有乙基，1b或苄基1d。当在HMPT中用苯氧钾处理时，这些溴化物可提供9-烷基-10-苯氧基蒽2和9-（α（苯氧基烷基）蒽3的混合物。另一方面，9-溴10异丙基蒽1c几乎没有反应性，而9-溴10异丙基蒽1c则没有反应。溴-d10-甲氧基甲基蒽1e基本上导致了蒽7。

  monomer fluorescence. The host–guest complexes of [9‐(S)PPh2‐10‐Ethyl‐(C14H8)] with four basic arenes reveal an emission enhancement up to five‐times higher quantum yields compared to the pure host. Less interchromophoric interactions and a restriction of intramolecular motion within the host molecules due to fixation by weak C−H⋅⋅⋅π interactions with the co‐crystallised arene are responsible for that

  显示出固态发光的小而坚固的有机分子是光电材料的有希望的候选者。在此，我们研究了一系列二苯基膦酰蒽[9-PPh 2 ‐10-R-(C 14 H 8 )]及其硫氧化类似物。氧化导致分子结构发生巨大变化，因为大体积 (S)PPh 2取代基的新取向诱导了蒽核的强烈蝶形弯曲结构，从而引发了强烈的红移，从而产生绿色固态荧光。由于发射特性在聚集时仅发生轻微变化，因此发射的起源归因于典型的单体荧光。[9-(S)PPh 2 ‐10-乙基-(C 14 H 8 )]与四种基本芳烃的主客体复合物显示出与纯主体相比，发射增强高达五倍的量子产率。由于与共结晶芳烃的弱 C−H⋅⋅⋅π 相互作用的固定，发色团间相互作用较少，并且主体分子内分子内运动受到限制，这是导致发射增强的原因。

  A photopolymerization initiator comprising (A) a photo acid-generating compound such as diaryliodonium salt (e.g., diphenyl iodonium, bis(p-chlorophenyl)iodonium, etc.,), (B) a photo oxidation radical-generating compound such as diarylketone compound, α-diketone compound or ketocoumarin compound, and (C) a fused polycyclic aromatic compound such as 1,4-dimethylnaphthalene, 1-methylanthracene, 9-methylanthracene, 9,10-dimethylanthracene or 9,10-diethylanthracene. The photopolymerization initiator makes it possible to efficiently polymerize the cationically polymerizable monomer by the irradiation with visible light.

  A cationically curable composition for dental use containing a cationic polymerization initiator (I) and cationically polymerizable monomers (II), the cationically polymerizable monomers (II) containing an oxetane compound and an epoxy compound or an alkenyl ether compound at a ratio of amounts that satisfy the conditions expressed by the following formula,         (a x A) : (b x B) = 91 : 9 to 45 : 55    wherein A is a mol number of the oxetane compound, "a" is an average number of the oxetane functional group contained in one molecule of the oxetane compound, B is a mol number of the epoxy compound or the alkenyl ether compound, and "b" is an average number of the epoxy functional group contained in one molecule of the epoxy compound or an average number of the alkenyl ether functional group contained in one molecule of the alkenyl ether compound. The composition is not hindered by oxygen from being polymerized, cures quickly even without using a special polymerizable monomer or a particular polymerization initiator, little forms an unpolymerized layer on the surface even when polymerized and cured in a highly humid environment such as in the oral cavity, and is suited as a filling/restorative material for dental use.

  [Object] To provide a method of producing a plate denture using a stereolithography 3D printer, which is capable of producing a plate denture in a short time with a more simplified production process, the plate denture exhibiting excellent occlusion. [Solving Means] The problem is solved by a method of producing a plate denture, including: adhering an artificial tooth and a denture base photochemically solidified by a stereolithography 3D printer to each other by polymerizing an unpolymerized curable composition for stereolithography present on a surface of the denture base. Further, stronger adhesion between the artificial tooth and the denture base is achieved by mixing, in the curable composition for stereolithography, a polymerization initiator other than a photopolymerization initiator for stereolithography.
