Force-induced proportion color-changing material and preparation method thereof

The invention discloses a force-induced proportion color-changing material and a preparation method thereof. The preparation method comprises the following steps: dissolving 2,5-dibromobenzene-1,4-diformaldehyde, 4-diphenylamino-phenylboronic acid and tetrakis(triphenylphosphine)palladium in a solvent and an alkaline solution, heating, stirring and reacting, extracting the reaction liquid by an extraction system, carrying out column chromatography purification to obtain an intermediate; stirring and reacting the intermediate with 3,5-bis(trifluoromethyl)phenyl acetonitrile and sodium methoxidein an organic solvent at room temperature, treating the reaction system to obtain yellow powder, namely the target product cross-shaped diphenylvinylnitrile derivative, namely the force-induced proportion color-changing material. The invention provides the cross-shaped diphenylvinylnitrile derivative which is a force-induced proportion color-changing material, the color change is obvious, the orange becomes dark red, and the fluorescence color is gradually deepened along with the increase of the static pressure, the characteristics of being sensitive to external irritation and good in stability are achieved, and the color of the material changes in proportion by applying static pressure to the material, and the material can be used for pressure sensing elements and optical records.

Triphenylamine derivative and preparation method thereof

The invention discloses a triphenylamine derivative and a preparation method thereof. The synthesis method is simple and is easy to operate, and as compared with an original synthesis process, the reaction time is greatly shortened from the original 48 h to 40 min, the chemical environment is simpler in comparison with a reaction system, nitrogen protection and temperature increment are not needed, even a water solution can exist, and the productivity is relatively high and can reach 90 percent. The triphenylamine derivative (I) has the photoluminescence performance and can serve as a photoluminescence material.

A donor-acceptor cruciform π-system: High contrast mechanochromic properties and multicolour electrochromic behavior

A donor-acceptor (D-A) cruciform conjugated luminophore DMCS-TPA was designed and synthesized. The DMCS-TPA solid shows both aggregation induced emission (AIE) effect and high contrast mechanochromic (MC) behavior with a remarkable spectral shift of 87 nm. The obvious fluorescence switching from yellowish green to orange can be realized by pressing at only 10 MPa or simply grinding. The photophysical properties, theory calculation and XPS results demonstrate that the extension of the conjugation length and subsequent enhancement of intramolecular charge transfer (ICT) transition are responsible for the improved MC performance. In addition, DMCS-TPA is readily deposited on the ITO electrode surface by the electrochemical method to form an electrochromic (EC) film with multiple colours showing (light green at 0 V, red at 1 V, grey at 1.1 V and blue at 1.45 V) and a high optical contrast of 65% at 769 nm. The results suggest that incorporation of electroactive moieties into luminophores to constitute D-A cruciform conjugated structures is a promising design strategy for preparing dual functional materials combining MC and EC properties.
