Based on RAFT polymerization technology and DDMAT end capping active chain end, the core advantages of narrow molecular weight distribution and precise molecular weight control are achieved to achieve multifunctional expansion:
Block copolymer construction: As a macromolecular chain transfer agent, two-block/multi-block copolymers (such as PS-b-PAA) are synthesized, the hydrophobic ratio is precisely regulated, nano-self-assembly (microbes, vesicles), and adapted to pH-responsive drug delivery and tumor-targeted therapy.
Gentle functionalization: Convert the DDMAT chain end to a hydrogen end or targeting group (such as carboxyl, fluorescent label) through visible light catalytic desulfurization (blue light, room temperature) to diagnose probe or sensor surface modification to avoid structural damage by strong acids/bases.
