Abstract:The simultaneous pursuit of accelerative radiative and
restricted
nonradiative decay is of tremendous significance to construct high-luminescence-efficiency
fluorophores in the second near-infrared wavelength window (NIR-II),
which is seriously hindered by the energy gap laws. Herein, a mash-up
strategy of π-extension and deuteration is proposed to efficaciously
ameliorate the knotty problem. By extending the π-conjugation
of the aromatic fragment and introducing an isotope effect to the
aggregation-induced em… Show more
