Abstract
We describe a facile strategy, involving bio-inspired noncovalent molecular recognition, for fabricating water-dispersible luminescent polymer dots without any ionic groups. We first synthesized the thymine-functionalized conjugated polymers PC-T and PTC-T through conventional Suzuki coupling polymerization and copper(I)-catalyzed alkyne/azide cycloaddition (CuAAC). These multiple-hydrogen-bonding materials exhibited distinct luminescent properties in protic and aprotic solvents as well as attractive thermal properties and stabilities; most importantly, they had the ability to pair with complementary base units. Next, we prepared the hydrophilic polymer PEG-A and examined its molecular recognition with PC-T and PTC-T through DNA-like adenine–thymine (A–T) base pairing. We used transmission electron microscopy (TEM) and dynamic light scattering (DLS) to determine the size distributions and dispersibilities of the resulting supramolecular micelles, which appeared as polymeric dots with high signal-to-backgr...
