Abstract

Photomodulation of two-photon excited fluorescence has been effectively controlled in 1-pyrene-based dithienylethenes. The specific molecular design enables photocommutation of two-photon excited fluorescence during sequential one- and two-photon excitations without interference nor destructive optical readout. Theoretical studies have concluded that the internal functionalization of pyrene is responsible for the photoactivity in these systems. Photophysical studies indicate that the presence of a second laterally introduced pyrene is crucial for maintaining high photocommutation contrast and durability.

二噻吩双(1-芘基)化合物的双光子激发荧光的光调制：实验和理论研究

双光子激发荧光的光调节已被有效地控制在以 1-pyrene 为基础的二噻吩中。特定的分子设计使双光子激发的荧光在连续的单光子和双光子激发过程中发生光致变换，而不会产生干扰或破坏性的光学读数。理论研究认为，芘的内部官能化是这些系统产生光活性的原因。光物理研究表明，第二个横向引入的芘的存在对于保持高光致变换对比度和耐久性至关重要。

期刊介绍： Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied. Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media. The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
