Abstract

Orthogonally arranged π-electronic systems comprising directly connected electron-deficient and anion-responsive moieties were synthesized by the connection of acridine/N-methylacridinium and dipyrrolylpyrimidine (dpp) units. Acridine- and N-methylacridinium-substituted dpps showed anion-binding behaviors via hydrogen bonding at pyrrole NH and pyrimidine CH, suggesting the possibility of modulating the electronic states of the anion-responsive π-electronic systems. Transient absorption measurements of the acridine-substituted dpp revealed a photoinduced electron transfer from the anion-responsive unit to the electron-deficient moiety, which was accelerated by anion binding.

具有阴离子响应的正交排列π-电子体系表现出光致电子转移。

通过吖啶/ n-甲基吖啶和二吡咯基嘧啶（dpp）单元的连接，合成了由缺电子和阴离子响应组成的正交排列π-电子体系。吖啶和n-甲基吖啶取代的dpps通过在吡咯NH和嘧啶CH上的氢键表现出阴离子结合行为，表明可以调节阴离子响应π-电子体系的电子态。吖啶取代的dpp的瞬态吸收测量显示，阴离子响应单元向缺电子部分发生了光诱导电子转移，阴离子结合加速了这一过程。

期刊介绍： Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
