Hyperbranched polymers

A method for emitting light comprising exciting a hyperbranched polymer formed by copolycyclotrimerization of monomers of general formulae (I) and (II), wherein the monomers are:

• 62
• or salts thereof;
• X is selected from the group consisting of linear or cyclic optionally substituted alkylene, and optionally substituted arylene or heteroarylene;
• R1, R2, R3 and Y are independently selected from the group consisting of optionally substituted, optionally interrupted linear or cyclic alkyl, and optionally substituted aryl or heteroaryl;
• P and Q are independently selected from the group consisting of optionally substituted arylene or heteroarylene, optionally substituted linear or cyclic alkylene, and optionally substituted alkenylene of formula —(CR4=Z)p- or -(Z=CR4)p— where Z represents CR5 or N, R4 and R5 each independently represent a hydrogen atom or an optionally substituted alkyl group, and p≧1;
• and wherein m and n are independently 0, 1, 2 or 3.

A method for limiting the transmission of light comprising interposing a layer composed of a hyperbranched polymer formed from homopolycyclotrimerization of monomers of general formula (I) between a light source and another material, wherein the monomers are:

• 65
• or salts thereof;
• X is selected from the group consisting of linear or cyclic optionally substituted alkylene, and optionally substituted arylene or heteroarylene;
• R1 and R2 are independently selected from the group consisting of optionally substituted, optionally interrupted linear or cyclic alkyl, and optionally substituted aryl or;
• P and Q are independently selected from the group consisting of optionally substituted arylene or heteroarylene, optionally substituted linear or cyclic alkylene, and optionally substituted alkenylene of formula —(CR4=Z)p- or -(Z=CR4)p— where Z represents CR5 or N, R4 and R5 each independently represent a hydrogen atom or an optionally substituted alkyl group, and p≧1;
• and wherein m and n are independently 0, 1, 2 or 3.

• P and Q are independently selected from the group consisting of optionally substituted arylene or heteroarylene, optionally substituted linear or cyclic alkylene, and optionally substituted alkenylene of formula —(CR4=Z)p- or -(Z=CR4)p— where Z represents CR5 or N, R4 and R5 each independently represent a hydrogen atom or an optionally substituted alkyl group, and p≧1;
• and wherein m and n are independently 0, 1, 2 or 3;
• with the proviso that where X is a phenylene group or —CH2OC6H4OCH2—;
• R1, R2 and R3 are all hydrogen;
• and n and m are both equal to 0, Y is other than unsubstituted phenyl or a vinyl-substituted phenyl.
