摘要：Pure organic room-temperature phosphorescence (RTP) materials have attracted wide attention owing to their excellent luminescent properties and great potential in various applications. In this work, iminostilbene and its analogues are applied to realize RTP emission by copolymerizing with acrylamide. It can be concluded that the growth of alkane chain in monomers can enhance the lifetime and photoluminescence quantum yield of RTP emission, and polymers with the larger conjugated structure of the monomer show a longer RTP emission wavelength. This work provides a series of new pure organic RTP materials and might provide new thoughts for designing more advanced and superior RTP materials.
