Tetraphenylethylene-based fluorescent conjugated microporous polymers for fluorescent sensing trinitrophenol
نویسندگان
چکیده
Two tetraphenylethylene-based fluorescent conjugated microporous polymers (TTTPT and TTDAT) were obtained by the Friedel−Crafts polymerization reactions catalysed CH3SO3H. In virtue of containing tetraphenylethylene, triphenylamine s-triazine units in their porous skeletons, resulting TTTPT TTDAT show excellent fluorescence sensing performance for trinitrophenol (TNP) with high quenching coefficients 1.66 × 104 1.31 105 l mol–1, respectively. can also sense to dinitrophenol (DNP) Ksv 2.70 mol–1. The mechanisms selective detecting TNP attribute conventional photoinduced electron-transfer mechanism, absorption competition mechanism and/or resonant energy transfer mechanism.

Mechanically strong, fluorescent hydrogels from zwitterionic, fully π-conjugated polymers.
Mechanically strong supramolecular hydrogels (up to 98.9% water content) were obtained by the combination of a rigid, fully π-conjugated polymer backbone and zwitterionic side chains. The gels were characterized by SAXS, SEM and rheology measurements and are fluorescent, stimuli responsive (temperature, salts) and bind DNA.
متن کاملFluorescent nanoscale zinc(II)-carboxylate coordination polymers for explosive sensing.
Fluorescent nanoscale coordination polymers with cubic morphology and long range ordered structure were fabricated and exhibited efficient sensing for both nitroaromatic explosive and nitromethane due to large surface area to volume ratio and strong binding affinity to explosive molecules.
متن کاملNetwork formation mechanisms in conjugated microporous polymers
Microporous polymers are useful for heterogeneous catalysis, separations, sensing, and energy applications. For example, there has been much focus on the capture and separation of gases such as CO2 in microporous materials. 1,3–5 Porous polymers are a growing platform for such applications. The broad family of microporous polymers now comprises several different classes of materials, including ...
متن کاملExtended conjugated microporous polymers for photocatalytic hydrogen evolution from water.
Conjugated microporous polymers (CMPs) have been used as photocatalysts for hydrogen production from water in the presence of a sacrificial electron donor. The relative importance of the linker geometry, the co-monomer linker length, and the degree of planarisation were studied with respect to the photocatalytic hydrogen evolution rate.
متن کاملAn insulin-sensing sugar-based fluorescent hydrogel.
We have prepared a small library of amphiphiles, each comprising a polar carbohydrate head group attached through an N-terminal amino acid to a nonpolar pyrene tail group. One of these derivatives is sensitive to the presence of insulin in aqueous media.
