RSC Adv 2021; 11:30472-30478.

Abstract
The newly designed polythiophene chemosensors (PT1 and PT2) were synthesized via the Suzuki-Miyaura polymerization with appropriate yields. The photophysical properties of PTs thus obtained were examined by means of UV/vis, fluorescence, excitation spectroscopy, and time-correlated single-photon-counting method. The π-π* transitions around 400-600 nm and the emissions in the range of 400-650 nm were observed. The binding behavior of PTs was also investigated upon the interaction of tetrabutylammonium or tetrabutylphosphonium isophthalate, affording the binding constants (K) of 5790-8310 M-1, which were quite smaller than those observed in the corresponding repeating unit. The comprehensive analyses of the UV/vis data and theoretical calculation supports revealed the origins of scope and limitation toward signal-amplification sensing. The present results obtained herein will guide the development of new amplification chemosensors.

Abstract
The development of signal amplification systems has attracted much attention and presents a highly challenging objective. Herein, we reveal the amplification processes using a newly synthesized bisthiourea-binaphthyl-polythiophene conjugate. The spectral data, behavior of supramolecular complexation, and thermodynamic parameters with calculation support comprehensively elucidated the factors that control the outcomes of the signal amplification. The present work provides a new perspective on functional chemosensors and an attractive alternative to conventional amplification systems.
