The study of the chemical and electrochemical fluorescence switching properties of a family of substituted triphenylamine derivatives is reported. First of all, the synthesis of a family of six compounds is described. They are characterized by electrochemistry, UV-vis and fluorescence spectroscopy and spectroelectrochemistry. Theoretical calculations were performed in order to corroborate the experimental results. While these compounds emit blue to green light under UV irradiation with a large quantum yield (37%) in the case of one molecule, the fluorescence intensity is quenched upon oxidation. The fluorescence behavior can be switched between the strong fluorescent (neutral) state and the non-fluorescent (oxidized) state with a high contrast (around 1500 for the fluorescence intensity for one of these molecules). Furthermore, the chromatic contrast of three of these molecules reaches 70% that can be important for further applications. This journal is the Partner Organisations 2014.

Paragraph 0041-0043, (2020/05/30)
The invention discloses an ionic liquid containing a triphenylamine structure as well as a preparation method and application thereof, the ionic liquid containing the triphenylamine structure is shownas a formula (I), and the ionic liquid can be used as a polymerization monomer for electrochemical polymerization to form a film and applied to preparation of an electrochromic material. According tothe invention, a series of new ionic liquids which contain the triphenylamine structure and different kinds of anions and have electrochromic properties are synthesized, the kinds (electrochromic properties and electrolyte properties) of the multifunctional ionic liquids are expanded, and meanwhile, after the materials are subjected to electrochemical polymerization to form films, the response speed of the films is at a leading level in electrochromic materials. The ionic liquid materials with the electrochromic performance and the electrolyte function can be applied to design and assembly ofelectrochromic devices, and the structural composition of the devices is reduced. In the formula (I), X is BF4 , PF6 , TFSI or TOF .
