Self-assembling polymers—V

A diblock copolymer of the formula (I):

• wherein:
• R1 is a poly(alkyleneoxide) group of the formula, —(CHR—CH2—O)p—R′, wherein p=2-6, R is H or methyl, and R′ is H, a C1-C6 alkyl group, or a C3-C11 cycloalkyl group;
• R2 is a C1-C22 alkyl group or a C3-C11 cycloalkyl group, each optionally substituted with a substituent selected from halo, alkoxy, alkylcarbonyl, alkoxycarbonyl, amido, and nitro;
• one of R3 and R4 is a C6-C14 aryl group or a heteroaryl group, optionally substituted with a substituent selected from hydroxy, halo, amino, and nitro, and the other of R3 and R4 is a C1-C22 alkoxy group, optionally substituted with a substituent selected from carboxy, amino, mercapto, alkynyl, alkenyl, halo, azido, and heterocyclyl;
• and
• n and m are independently 2 to about 2000;
• wherein the volume fraction of the monomer bearing R2 to that of the monomer bearing R1 in the block copolymer is about 2.8:1.
