A method of synthesizing a two-photon active tris(diarylamino-9,9-di(R)fluorenyl)-1,3,5-triazine compound having the structure:
where Y is hydrogen, a thermally self-polymerizable acrylic, or a methacrylic group; R is an alkyl group of the formula —C
m
H

p
Me, wherein the subscript p ranges from 1 to 5; R′ is an alkyl group; and the R′—(OY)
x
groups are attached to the phenyl rings of the triarylamine moiety either in a para position or a meta position and the subscript x ranges from 1 to 3. The compound may be synthesized by (a) synthesizing a diarylamine intermediate, (b) synthesizing a brominated 1,3,5-triazine intermediate as a three-arm core structure, and (c) forming the two-photon active tris(diarylamino-9,9-di(R)fluorenyl)-1,3,5-triazine compound by covalently joining the diarylamine and each arm of the three-arm core structure and removing the acetone protecting groups. The diarylamine intermediate may be synthesized by protecting tris-1,1,1-(hydroxymethyl)ethane, via a ketal formation with acetone, as an acetonide derivative; furnishing bromophenoxy-methyltrimethyl-1,3-dioxane from the acetonide derivative; and arylating aniline with the bromophenoxy-methyltrimethyl-1,3-dioxane.
一种合成具有结构的双光子活性三(diarylamino-9,9-二(R)芴基)-1,3,5-三嗪化合物的方法:其中Y为氢、热自聚丙烯酸或甲基丙烯酸基团;R为公式—CmH2m+1的烷基,其中下标m范围为1至6,或公式—(CH2CH2O)pMe的烷基醚基团,其中下标p范围为1至5;R'为烷基;而R'-(OY)x基团附着于三芳基胺基团的苯环的邻位或间位,其中下标x范围为1至3。该化合物可通过以下步骤合成:(a)合成二芳基胺中间体,(b)合成溴代1,3,5-三嗪中间体作为三臂核结构,(c)通过共价连接二芳基胺和三臂核结构的每个臂,去除丙酮保护基,形成双光子活性三(diarylamino-9,9-二(R)芴基)-1,3,5-三嗪化合物。二芳基胺中间体可以通过以下步骤合成:使用丙酮进行醇缩形成丙酮烯醇衍生物保护三-1,1,1-(羟甲基)乙烷为乙二醇缩合物;从乙二醇缩合物中得到溴苯氧甲基三甲基-1,3-二噁烷;然后用溴苯氧甲基三甲基-1,3-二噁烷进行芳基化反应。
