Abstract Smart materials enabling emission intensity or wavelength tuning by light stimulus have attracted attention in cutting‐edge fields. However, due to the general limitation of dense molecular stacking (in solid states, especially crystals) on photoresponsivity, constructing rapidly phototunable solid‐state luminescent systems remains challenging. Herein, we present a new luminophore that serves as both photoresponsive and luminous group with enhanced conformational freedom attain this goal, namely, relying photoexcitation‐induced change an ionized persulfurated arene based weak intermolecular aliphatic C−H⋅⋅⋅π interaction. Together phosphorescence characteristic molecule itself, upon irradiation can be observed series phase like solution state, crystal, amorphous high rate 0.033 s −1 crystal state is superior relevant reported cases. Moreover, afterglow effect achieved extending into some polymer‐based doping systems, endowing system unique dynamic imaging fast photopatterning capabilities. This single‐luminophore engineering underlying mechanism implications for building other condensed functional materials, principally those stimuli responses states.

Abstract The development of pure organic photosensitizers remains challenging due to low intersystem crossing (ISC) efficiency and the instability triplet excitons. Herein, a series phosphorescent molecules are prepared as photosensitizers. extensive conjugation fused-ring cores enhances visible-light absorption, while heteroatom-rich structures promote ISC process, effectively generating 2,3,5,6,9,10-Hexabutoxy-8-phenyldithieno-triphenyleno-pyridine (TPy) exhibits high can sensitize Fe-catalyst efficiently for photoreduction CO2-to-CO. A novel strategy doping into core amphiphilic nanoparticles (NPs) formed by polystyrene-block-poly(ethylene glycol) (PS-b-PEG) was further developed. PS, NPs, stabilize excitons generated TPy its rigid polymer backbone, resulting in enhanced photocatalytic efficiency. Meanwhile, PEG serves corona improving stability dispersibility. Notably, this self-assembled increases sensitization (TONCAT = 2041, 51.02 µmol CO) nearly 50%, even after three catalytic cycles, 93.5% original ability is retained. This result opens new avenue developing molecular stabilizing their excited-states efficient application photoredox reactions.
