We exploited a unique porous structure of the nano-covalent triazine polymer (NCTP) containing aggregation-induced emission (AIE) group to achieve controlled release and drug tracking in tumor acidic microenvironment.NCTP was synthesized by the Friedel-Crafts alkylation and the McMurry coupling reaction.It not only had strong doxorubicin (DOX)-Ioading capacity due to its high specific surface area and large pore volume,but also showed the significant cumulative drug release as a result of the pH response of triazine polymers.NCTP was induced luminescence after mass accumulation near tumor cells.Besides,it had excellent biocompatibility and obvious antineoplastic toxicity.The results demonstrate that NCTP as a utility-type drug carrier provides a new route for designing the multi-functional drug delivery platform.
