Published: Sept. 14, 2022

Nanomedicines for drug delivery and imaging-guided cancer therapy is a rapidly growing research area. The unique properties of nanomedicines have massive potential in solving longstanding challenges existing drugs, such as poor localization at the tumor site, high doses toxicity, recurrence, immune response. However, inadequate biocompatibility restricts their clinical translation. Therefore, advanced nanomaterials with enhanced therapeutic efficiency are highly desired to fast-track translation nanomedicines. Intrinsic nanoscale covalent organic frameworks (nCOFs), suitable size, modular pore geometry porosity, straightforward post-synthetic modification via simple transformations, make them incredibly attractive future ability COFs disintegrate slightly acidic microenvironment also gives competitive advantage targeted delivery. This review summarizes recently published applications delivery, photo-immuno therapy, sonodynamic photothermal chemotherapy, pyroptosis, combination therapy. Herein we mainly focused on modifications enhance biocompatibility, efficacy will provide fundamental knowledge designing biocompatible nCOFs-based help rapid development carriers theranostics.

Excited-state intramolecular proton transfer (ESIPT) has been widely employed for the design of a variety functionality-led molecular systems. However, precise manipulation excited-state reaction is challenging. Herein, we report new tactic tuning ESIPT via incorporating an charge (ESICT) process. Specifically, three o-carborane derivatives, NaCBO, PaCBO, and PyCBO, were designed, where 2-(2'-hydroxyphenyl)-benzothiazole typical unit functioning as electron acceptor, electron-donating units are naphthyl-(Na), phenanthrenyl-(Pa), pyrenyl-(Py), respectively. The architectures molecules featured with face-to-face alignment two units. Spectroscopy theoretical calculation studies revealed that capacity donors solvent polarity continuously modulate ESIPT/ESICT energetics dynamics, resulting in distinct emissions. Moreover, depicted not only highly porous structures but also very different fluorescent colors solid state, enabling selective film-based fluorescence sensing mustard gas simulant, 2-chloroethyl ethyl sulfide, detection limit 50 ppb response time 5 s. This work thus provides reliable strategy creation high-performance fluorophores manipulation.
