资源简介：
Peripherally substituted tetradecaazaheptacene
(N14Hp) compounds, exhibiting amphiprotism-coupled emission,
have been
synthesized. X-ray crystallography reveals a planar acene-like chromophore,
and electronic absorption and emission occur in the near-infrared
biological transparency window (650–900 nm). The compounds
exhibit long-wavelength emission with photoluminescence quantum yields
ΦPL up to ∼0.61 at 686 nm, with the monodeprotonated
state ΦPL ≈ 0.58 at 712 nm. This unprecedented
highly nitrogenous chromophore illustrates the stability and utility
of the pyrazinacenes for different applications based on their photophysical
properties and chemical structures.
