      abstract     = {Low-dimensional hybrid perovskites have demonstrated
                      excellent performance as white-light emitters. The broadband
                      white emission originates from self-trapped excitons (STEs).
                      Since the mechanism of STEs formation in perovskites is
                      still not clear, preparing new low-dimensional white
                      perovskites relies mostly on screening lots of intercalated
                      organic molecules rather than rational design. Here, we
                      report an atom-substituting strategy to trigger STEs
                      formation in layered perovskites. Halogen-substituted phenyl
                      molecules are applied to synthesize perovskite crystals. The
                      halogen-substituents will withdraw electrons from the
                      branched chain (-R-NH3+) of the phenyl molecule. This will
                      result in positive charge accumulation on -R-NH3+, and thus
                      stronger Coulomb force of bond (-R-NH3+)-(PbBr42−), which
                      facilitates excitons self-trapping. Our designed white
                      perovskites exhibit photoluminescence quantum yield of
                      $32\%,$ color-rendering index of near 90 and chromaticity
                      coordinates close to standard white-light. Our joint
                      experiment-theory study provides insights into the STEs
                      formation in perovskites and will benefit tailoring white
                      perovskites with boosting performance.},
