Application of double click to prepare near-infrared absorbing dye for photo-thermal tuning of cholesteric liquid crystal

Cholesteric liquid crystal (CLC) exhibits selective reflection, making it a great application in the field of light control. Here, a near-infrared light (NIR) was used to drive the self-organizing spiral superstructure of the cholesteric liquid crystal to

Reversible mechanofluorochromism of aniline-terminated phenylene ethynylenes

Seven three-ring phenylene-ethynylene (PE) structural analogs, differing only in the lengths of alkyl chains on terminal aniline substituents, show 50-62 nm bathochromic shifts in emission maxima in response to mechanical force (mechanofluorochromism, MC)

Charge transfer NIR dyes for improved photoacoustic effect

A new class of NIR absorbing dyes accessed by a cycloaddition-cycloreversion reaction of alkynes with 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane is reported. The photoacoustic effect of the new NIR dyes was systematically studied. The results va

Nonlinear optical and energy-level modulation of organic alkynes by click chemistry

A series of novel donor–acceptor chromophores have been successfully synthesized in excellent yield by metal-free [2+2] click chemistry, which was effective in the energy-level modulation of organic the π-conjugation aniline derivatives. Meanwhile, struct

Synthesis, characterization and DFT calculations of new ethynyl-bridged C60 derivatives

A new series of soluble C60 derivatives for organic electronic application has been synthesized by ethynylation reaction using different electron-donating and electron-withdrawing groups of varying length.
