To gain insights into the coupling of conformational and electronic variables, we exploited steric hindrance to modulate a polycyclic skeleton with bent conformation in S0 state twisted S1 under guidance photoexcited aromaticity reversals. Polycyclic 5,10-dihydrophenazine (DHP) adopted structure but involved bent-to-planar transformation due excited-state 8π-electron central ring. The N,N'-locations 1,4,6,9-sites DHP provided versatile chemical handle for fine-tuning intramolecular...

Simple donor–acceptor (D–A) molecules with large Stokes-shifted and bright near-infrared (NIR) emissions are extremely attractive for the high-resolution three-photon fluorescence (3PF) imaging of deep tissues. Herein, we present a new strategy significantly extending Stokes shifts D–A fluorophores, relying on increasing excited-state structural/electronic relaxation donor moiety. The prototype structure DPCN, containing planar N,N′-diphenyl-dihydrophenazine (DHP) acceptor malononitrile,...

Radionuclides, such as strontium (Sr), are hazardous radioactive isotopes commonly found in nuclear waste, posing serious environmental and health risks due to their long half-lives ability bioaccumulate. Inspired by the electronic modification effect, this study theoretically predicts that doping can significantly enhance adsorptive performance of MXenes for radionuclides. Specifically, we employed comprehensive first-principles simulations investigate impact nitrogen (N) on adsorption...
