Claim 0:
1. A method for preparing heteroatom doped polymer nanospheres, comprising:
(1) dissolving aromatic amine and a compound of formula I in water at 10-50° C. to obtain a first mixture, wherein the compound of formula I is, wherein:
R1 is H or NH2,
R2 is selected from the group consisting of H, COOH, SO3H, B(OH)2, OPO(OH)2, Cl, OCH3, CN, OH, SH, and NO2, and
R3 is H or SO3H;
(2) adding aqueous ammonia to the first mixture under stirring to obtain a second mixture;
(3) adding aldehyde to the second mixture and reacting under stirring to obtain a third mixture comprising polymer nanospheres,
wherein the aromatic amine in step (1) is selected from the group consisting of melamine, 1,3-phenylenediamine, 1,4-phenylenediamine, 1,3-xylylenediamine, 1,4-xylylenediamine, tris(4-aminophenyl)amine, 2,4,6-triaminopyrimidine, 2,6-diaminopyridine, 1,5-diaminonaphthalene, 1,4-diaminonaphthalene, 2,3-diaminonaphthalene, 1,8-diaminonaphthalene, and mixtures thereof.
