The invention relates to a fluorescent ion probe (I) with high selectivity and high sensitivity in detection and the application of the fluorescent ion probe in identifying and detecting heavy metal ion and transition metal ion, wherein, the Y is an organic conjugate group with fluorescence transmitting function such as pyrene, naphthalene, 4-amidogen-1, 8-naphthyl imide, Dan sulfonamide, anthracene, carbazole, benzimidazoins, benzoxazoles, boron fluoride bipyrrole (BODIPY), fluorescein, 3, 4, 9, 10-perylenetetracarboxylic diimide or rhodamine B; the X is acylamino group, sulfoamino group or ester group. The fluorescent ion probe uses the fluorescence peak of fluorescence chromophore aggregate as the response signal to identify metal ion, thereby effectively avoiding the quenching effect of transition metal ion and heavy metal ion on fluorophore; moreover, the fluorescent ion probe realizes selective identification of heavy metal ion and transition metal ion in various solvents and aqueous solution in particular.

The invention provides a positive-working planographic printing plate precursor excellent in printing durability and chemical resistance.

The invention provides a chiral sulfinylamine monophosphine and a preparation method thereof. The preparation method comprises the following steps: carrying out a condensation reaction of 2-disubstituted phosphinoaryl(heteroaryl)formaldehyde (ketone) 2 and chiral sulfonamide 3 to obtain a compound 4, and reacting the compound 4 with a nucleophilic reagent to prepare a compound 1; or carrying out a condensation reaction of aldehyde (ketone) 5 and the chiral sulfonamide 3 to obtain imine 6, and reacting the imine 6 with a 2-disubstituted phosphinoaryl(heteroaryl) metal reagent to obtain the compound 1; or reacting the imine 6 with the 2-disubstituted phosphinoaryl(heteroaryl) metal reagent to obtain a compound, and reducing the compound to obtain the compound 1; or carrying out a condensation reaction of 2-substituted phosphinoaryl(heteroaryl)formaldehyde (ketone) 8 and the chiral sulfonamide 3 to obtain an imine compound 9, reacting the imine compound 9 with the nucleophilic reagent to obtain a compound 7, and reducing the compound 7 to obtain the compound 1. Different chiral sulfenamides and different metal reagents are used to conveniently obtain the optically pure compound of four configurations comprising (R,R), (R,S), (S,S) and (S,R). The above ligand has the advantages of simple skeleton, synthesis convenience and easy reconstruction, can be applied in various metal-catalyzed asymmetric reactions, and has a very high reaction activity and stereoselectivity.
