The synthesis of C3-symmetrical tristriazolotriazines with conjugated arms and lateral alkoxy side chains was performed by a threefold condensation of cyanuric chloride with tetrazoles. Conjugated π segments include phenyl, tolane, and its phenylethynyl-elongated homologue. Disclike and a dendritic molecule have been obtained, and two compounds with a 3,4,5-tris(octyloxy) substitution form broad thermotropic
具有共轭臂和侧链烷氧基侧链的 C3 对称三唑并三嗪的合成是通过三聚氯氰与四唑的三重缩合来进行的。共轭 π 链段包括苯基、甲苯烷及其苯基乙炔基延伸的同系物。已获得盘状和树枝状分子,并且具有 3,4,5-三(辛氧基)取代基的两种化合物形成宽的热致中间相。报告了线性光学特性、荧光的溶剂致变色、酸致变色和所选化合物的双光子吸收效率。
