Multicolored near-infrared electrochromic polyimides: Synthesis, electrochemical, and electrochromic properties

A novel series of multicolored near-infrared electrochromic aromatic polyimides have been synthesized by a conventional two-step polymerization process. All polymers displayed outstanding thermal stability, i.e. 20 wt% loss in excess of 593 C in nitrogen and high char yields (higher than 68% at 750 C). In addition, the polymer films showed reversible electrochemical oxidation, high coloration efficiency, low switching time, and anodic green electrochromic behaviors. The Highest Occupied Molecular Orbital (HOMO) and Lowest Unoccupied Molecular Orbital (LUMO) energy levels of these polymers were determined in the range of -4.759 to -4.801 and -1.758 to -2.002 eV (vs the vacuum level) by cyclic voltammetry method consisting with the results of quantum chemical calculation well, respectively. The polymer films revealed excellent stability of electrochromic characteristics for the radical cations generated, changing color from original yellowish to green and blue, with the absorption changing from ultraviolet to near-infrared.

Diamine compound containing symmetrical bifluorophore structure and preparation and application thereof Polyamide and polyimide and preparation and application thereof

The invention provides a diamine compound containing a symmetric bifluorophore structure and preparation and application thereof, polyamide and polyimide as well as preparation and application thereof, and belongs to the technical field of electric control fluorescence. In the diamine compound structure provided by the invention, the highly symmetric diphenylamine group serves as the derivative structure of triphenylamine, the stability of the monocationic radical can be remarkably enhanced due to the resonance coupling action between the two N atoms, and the longer conjugation length phase makes it higher HOMO energy level and lower oxidation potential than monotriphenylamine. In addition, the polymer prepared by the diamine compound is high in fluorescence contrast ratio and short in fluorescence switching time.

Multifunctional polyurethanes synthesized from different triarylamine units with electrochromic, photogeneration, memory storage and sensing properties

In this work, a series of multifunctional polyurethane (PU) materials containing three kinds of different triarylamine (TAA) units was prepared. These polymers show good solubility in common organic solvents and excellent thermal stability under a N2 atmosphere. The PU films show reversible color changes with high contrast ratios and electrochromic stability. Moreover, they have good memory storage performance. The ON/OFF current ratio is about two orders of magnitude. Meanwhile, they can be used as detectors for 2,4,6-trinitrotoluene (TNT) and 2,4,6-trinitrophenol (TNP). The polymer solutions rapidly exhibit fluorescence-quenching phenomena when exposed to trace amounts of TNT and TNP. The PU films also have mechanical properties that make them suitable for use in stretchable devices.

Triarylamine-containing oxazine polymer and preparation method and application thereof

A triarylamine-containing oxazine polymer and a preparation method and application thereof are disclosed. The invention relates to a triarylamine-containing oxazine polymer and a preparation method and application thereof. The invention is to solve the problem that the conventional triarylamine-based polymer has poor heat resistance and an electrochromic polymer film has poor film attaching ability. According to the invention, N,N'-di-naphthyl-1,4-phenylenediamine, which is used as a raw material, reacts with p-fluoronitrobenzene to realize nitration, and then nitro group is reduced to an amino group; and bisphenol A, paraformaldehyde and the prepared triphenylamine-based monomer are used as raw materials to undergo a condensation reaction under a certain conditions to synthesize a polymer. The polymer has excellent electrochromic property and memory performance, can be applied in the field of electrochromism, and also performs well in explosives detection. The invention is applied inthe field of electrochromic polymers.
