  Mechanochromic Luminescence Quenching: Force-Enhanced Singlet-to-Triplet Intersystem Crossing for Iodide-Substituted Difluoroboron−Dibenzoylmethane−Dodecane in the Solid State

  摘要：

  A lipid derivative of difluoroboron-iododibenzoylmethane (BF2-dbm(I)OC12H25) was synthesized via Claisen condensation and boronation. Green photoluminescence is observed for the complex in the solid state. Unlike the previously reported difluoroboron-avobenzone (BF(2)AVB) complex, which exhibited significantly red-shifted fluorescence upon mechanical perturbation, the emission of a BF(2)dbm(I)OC12H25 solid film is quenched when the sample is smeared under air but becomes orange under nitrogen. Spectroscopic and lifetime studies suggest that smearing brings the singlet excited state closer to the triplet state, thus increasing the coupling between the two states. As a result, intersystem crossing from the singlet to the triplet excited state is facilitated, and the total luminescence intensity is quenched at room temperature.

  Halide-substituted difluoroboron β-diketonates were synthesized and display mechanochromic luminescence and quenching. Material structure is halide dependent and dynamic recovery properties for halide dyes are slower than for the hydrogen counterpart.

  卤代取代的二氟硼β-二酮酸盐被合成并显示机械致变发光和猝灭。材料结构取决于卤素，卤素染料的动态恢复性质比氢的对应物慢。
