Visible-light absorbing metal-free organic dyes are of increasing demand for various optoelectronic applications because of their great structure-function tunability through chemical means. Several dyes also show huge potential in triplet photosensitization, generating reactive singlet oxygen. Understanding the structure-property relationships of many well-known fluorescein dyes is of paramount importance in designing next-generation energy efficient dyes, which is currently limited.

Improving fluorescence emission efficiency is essential to develop novel luminescent materials. However, the low water solubility of conventional fluorescent dyes is a serious obstacle to broadening the application scope. Herein, a green protocol have been proposed: Two poorly water-soluble naphthalimide derivatives MONI and MANI with high fluorescent quantum yields (larger than 0.

Working to all orders in dimensionally regularized QCD with massless quarks, we study the radiation of a photon whose energy is much lower than that of external partons. The conventional soft photon theorem receives corrections at leading power in the photon energy, associated with soft virtual loops of massless fermions. These additive corrections give an overall factor times the nonradiative amplitude that is infrared finite and real to all orders in α_{s}.

In organic light-emitting diodes (OLEDs), only 25% of electrically generated excitons are in a singlet state, , and the remaining 75% are in a triplet state, . In thermally activated delayed fluorescence (TADF) chromophores the transition from the nonradiative state to the radiative state can be thermally activated, which improves the efficiency of OLEDs. Chromophores with inverted energy ordering of and states, < , are superior to TADF chromophores, thanks to the absence of an energy barrier for the transition from to .
