Abstract

A subporphyrazine (SubPz)-dithienylethene (DTE) photochromic device with and states, was developed and characterized. In this device, the DTE unit can reversibly switch the SubPz absorbance from green to near-infrared [λ (o/c) = 527 nm/740 nm], as well as the SubPz fluorescence and singlet oxygen quantum yields. The core of this design involves using a highly tunable SubPz chromophore that shares its quasi-isolated ethene moiety with a DTE photoswitch.

摘要

一种具有开和关两种状态的亚卟啉（SubPz）-二噻吩乙烯（DTE）光致变色器件被研发并进行了表征。在该器件中，DTE单元可将SubPz的吸光度从绿色可逆地切换至近红外[λ（开/关）=527纳米/740纳米]，同时还能切换SubPz的荧光和单线态氧量子产率。该设计的核心在于使用一种高度可调谐的SubPz发色团，它与一个DTE光开关共享其准孤立的乙烯部分。
