Nowadays,the development of triplet-involved materials becomes a hot research topic in solid-state luminescence fields.However,the mechanism of triplet-involved emission still remains some mysteries to conquer.Here,we proposed a new concept of excited-state conformation capture for the constructions of different types of triplet-involved materials.Firstly,excited-state conformation could be trapped by supramolecular chains in crystal and form a new optimum excited-state structure which is different from that in solution or simple rigid environment,leading to bright thermally activated delayed fluorescence(TADF)emission.Based on excited-state conformation capture methodology,next,we obtained room-temperature phosphorescence(RTP)by introducing Br atoms for the enhancement of intersystem crossing.It could be concluded from experimental results that TADF may originate from aggregate effect while RTP may derive from monomers.Finally,heavy-atom free RTP and ultra RTP were achieved by eliminating aggregate effect.This work could not only extend the design methodology of triplet-involved materials but also set clear evidences for the mechanism of triplet-involved emissions.
