Method for producing substrate having dispersed particles of dendrimer compound on the surface thereof, and substrate having dispersed particles of dendrimer compound on the surface thereof

A method for producing a substrate having dispersed particles of a dendrimer compound on the surface thereof, the method comprising:

• an application step including dissolving a phenyl azomethine dendrimer compound represented by the following general formula (1) in a solvent to prepare a solution, and applying the solution on the surface of a substrate;
• and a volatilization step including volatilizing the solvent from the solution applied on the surface of the substrate,
• the concentration of the phenyl azomethine dendrimer compound contained in the solution is no greater than 5 μmol/L:
• ABnRm (1)
• wherein A in the above general formula (1) is a core molecular group of the phenyl azomethine dendrimer and represented by a structure of the following formula:
• R1(—N═)p
• wherein R1 represents an aromatic group that may have a substituent, and p represents the number of bonds to the R1;
• and
• B in the above general formula (1) is represented by a structure of the following formula:
• in which one azomethine bond is formed for the A, the R2 represents an aromatic group that may have the same or different substituent;
• the R in the above general formula (1) is represented by a structure of the following formula:
• in which an azomethine bond is formed to the B as a terminal group, and the R3 represents an aromatic group that may have the same or different substituent;
• n represents a generation number through a structure of the B of the phenyl azomethine dendrimer;
• and
• m represents the number of terminal groups R of the phenyl azomethine dendrimer, and m is equal to p provided that n is 0, whereas m is equal to 2np provided that n is no less than 1.
