The invention relates to a preparation method of a ternary terbium complex monomer and a copolymer luminescent material of the ternary terbium complex monomer and MMA. The method comprises the steps that firstly, the ternary terbium complex monomer is prepared, and recrystallization is conducted on an initiating agent AIBN (azodiisobutyronitrile) through methyl alcohol; then the ternary terbium complex monomer is dissolved by utilizing DMF (N,N-dimethylformamide) and DMSO (dimethyl sulfoxide) or a toluene solvent respectively, wherein the molar ratio of the ternary terbium complex monomer to the MMA is 1-10 to 100, and the initiating agent AIBN accounts for 0.5%-1% of the total mass of an initiating system; after reaction is conducted for 20-60 h under the conditions that inert gas argon exists, water and oxygen do not exist, and the temperature ranges from 50 DEG C to 85 DEG C, copolymer powder is obtained through methyl alcohol reprecipitation. The copolymer can be used for electronic terminals such as computers, televisions and mobile phones and mainly serves as the luminescent material of the panel display field. In addition, due to the fact that a pendant group -N-H- of the copolymer contains a reactive hydrogen atom, the copolymer can be used for ion recognition and fluorescent probes.

The invention discloses a polyester/polyethyleneglycol block copolymer containing hydroxyl pendant group and application of the polyester/polyethyleneglycol block copolymer. The copolymer is an ABA type, (AB)2-100 type, AB type or BAB type block copolymer composed of the hydrophobic polyester block A containing the hydroxyl pendant group and the hydrophilic polyethyleneglycol block by mass ratio. The copolymer can be assembled into nano-particles in a water medium and used for entrapping drugs, protein, polypeptide and polysaccharide, and can also react with active functional groups to obtain other functional copolymers. The copolymer has good biological compatibility and biodegradablility, is easy to be assembled to form the nano-particles in water, and can be used as a carrier of drugs. The hydroxyl of the polyester block is an active group and can be subjected to bonding reaction with various biological factors, drugs or other functional groups, and therefore, application range of the nano-particles is expanded.
