Abstract

In order to regulate intermolecular interactions by altering the position of substituents, three positional isomers PAD, OAD and DAP have been designed and synthesized. PAD, OAD and DAP exhibited ICT behaviors. PAD and OAD have reversible MFC behaviors, and the emission maximum exhibited red-shift about 25 nm and 35 nm after grinding, respectively, simultaneously accompanied by color changes from blue to green. However, DAP did not exhibit susceptibility to external force stimuli. The present study demonstrated that the position isomerism of substituents had a significant impact on MFC properties, and the MFC behavior can be regulated by regulating the position of substituents.

酰基腙衍生物的机械荧光性：位置异构效应

为了通过改变取代基的位置来调节分子间的相互作用，设计并合成了三种位置异构体PAD、OAD和DAP。PAD、OAD和DAP表现出ICT行为。PAD和OAD具有可逆的MFC行为，磨削后发射最大值分别为25 nm和35 nm左右的红移，同时颜色由蓝变绿。然而，DAP对外力刺激没有表现出易感性。本研究表明取代基的位置异构对MFC的性质有显著影响，并且可以通过调节取代基的位置来调节MFC的行为。

期刊介绍： The purpose of the Journal of Luminescence is to provide a means of communication between scientists in different disciplines who share a common interest in the electronic excited states of molecular, ionic and covalent systems, whether crystalline, amorphous, or liquid. We invite original papers and reviews on such subjects as: exciton and polariton dynamics, dynamics of localized excited states, energy and charge transport in ordered and disordered systems, radiative and non-radiative recombination, relaxation processes, vibronic interactions in electronic excited states, photochemistry in condensed systems, excited state resonance, double resonance, spin dynamics, selective excitation spectroscopy, hole burning, coherent processes in excited states, (e.g. coherent optical transients, photon echoes, transient gratings), multiphoton processes, optical bistability, photochromism, and new techniques for the study of excited states. This list is not intended to be exhaustive. Papers in the traditional areas of optical spectroscopy (absorption, MCD, luminescence, Raman scattering) are welcome. Papers on applications (phosphors, scintillators, electro- and cathodo-luminescence, radiography, bioimaging, solar energy, energy conversion, etc.) are also welcome if they present results of scientific, rather than only technological interest. However, papers containing purely theoretical results, not related to phenomena in the excited states, as well as papers using luminescence spectroscopy to perform routine analytical chemistry or biochemistry procedures, are outside the scope of the journal. Some exceptions will be possible at the discretion of the editors.
