“…[4,9,[29][30][31][32][33][34] Thee xistence of strong intermolecular interactions,f or example, p-p interactions in the aggregated state of many RTPl uminogens,c an enforce intermolecular electronic coupling and reduce nonradiative transitions from T 1 to S 0 ,which contributes to more persistent RTP ( Figure 1a). [13,16,[30][31][32][35][36][37] Tr aditionally,t his goal is mainly achieved by decorating electron-withdrawing functional groups (EWGs) on the p system to relieve the p-p repulsion or/and constructing donor-acceptor (D-A)-type molecules to increase the intermolecular electrostatic interactions or dipole-dipole interactions between neighboring p systems ( Figure 1b and Chart S1). [23,30,32,[37][38][39][40] However,c oncise yet efficient molecular design tactics to modulate the p-p interactions and molecular packing of RTPl uminogens are still needed.…”
