Nanoluminophores Composed of 1,1′-Ferrocenedicarboxylic Acid and Tetrakis-(4-carboxyphenyl) Porphyrin for Electrochemiluminescence Sensing

Abstract: Development of nanoluminophores with high efficiency, good stability, and excellent electronic transfer ability is one of the key challenges in electrochemiluminescence (ECL). Here, a porphyrin-based nanomaterial named Fc-TCPP was synthesized by self-assembly of 1,1′-ferrocenedicarboxylic acid (Fc(COOH)2) and tetrakis-(4-carboxyphenyl) porphyrin (TCPP) under infrared heating light. By tuning the ratio of the precursors, the morphology of Fc-TCPP can be regulated from primitive nanospheres to thorn-ball flowers… Show more

“…The corresponding excited states (TCPP-Zn* and 1 O 2 *) and anions (TCPP-Zn 2– and O 2 2– ) were gained through electron transfer between the anion radicals TCPP-Zn •– and O 2•– . Finally, the overlapping cathode ECL luminescence was radiated . The equation is shown in eq S2.…”

“…Hence, porphyrin has attracted wide attention for use in ECL sensors. 9 Previous studies have demonstrated that forming a zinc complex by introducing metallic zinc into organic luminophor can improve the optical properties. 10 The study of tetraphenylporphyrin and its zinc complex has found that the generation pathways of the excited state were changed after zinc coordination, thus improving ECL performances.…”

“…As an ingenious combination of electrochemistry and chemiluminescence, electrochemiluminescence (ECL) is high-profile for its near-zero background and high controllability and sensitivity, resulting in its widespread application in biosensing and optoelectronic devices. High-efficient luminophors are inarguably the most critical part in the ECL assay. Among the reported electrochemiluminophors, porphyrins have become concerned ECL emitters due to their excellent physicochemical and electronic properties. Nevertheless, porphyrins are prone to undergo aggregation-caused quenching (ACQ) of light emissions in aqueous solutions, thus leading to unsatisfactory ECL emission, which hampered their further application. …”
